Introduction  
INTRODUCTION  
Thank you for purchasing the Internet Sharing Hub, MIH-108  
PalmRouter Elite. The PalmRouter Elite functions as an easy-to-use commu-  
nication device allowing you to connect a local area network (LAN) to the  
Internet. The PalmRouter Elite provides a convenient and economical solu-  
tion for small office or home office (SOHO) users who want access to the  
Internet at a lower cost.  
Sharing Internet Access  
The PalmRouter Elite provides high-speed Internet access to multiple  
users by sharing the bandwidth of up to two dial-up accounts. It comes  
equipped with two serial ports that can function as dial-on-demand dial-out  
ports. The first serial port dials out when a request for the Internet is made.  
The secondary serial port dials out when the bandwidth of the first serial port  
has reached its limit. When users log off and the network traffic jam has been  
relieved, the secondary serial port disconnects automatically. If no request is  
made for Internet resources for a period of time, the PalmRouter Elite discon-  
nects the first serial port automatically.  
Modems Supported  
The PalmRouter Elite supports 28.8/33.6/56K modems, ISDN TAs and  
leased-line connections. Up to two modems can be connected simultaneously  
to increase total bandwidth.  
Authentication Protocol Supported  
The PalmRouter Elite supports PAP/CHAP authentication protocols and  
login scripts for PPP dial-up connections.  
Built-in DHCP Server  
The PalmRouter Elite allows for automatic TCP/IP configuration on com-  
puters over the LAN. The built-in DHCP server dramatically reduces the con-  
figuration and maintenance effort.

Introduction  
8-Port Ethernet Hub Inside  
In addition to Internet sharing capability, the PalmRouter Elite also func-  
tions as an Ethernet hub. It has eight 10BASE-T RJ-45 ports, allowing users  
to connect with a small LAN.  
Easy Configuration  
The PalmRouter Elite can be configured through a Web browser, and fea-  
tures Web-based management for a simple, intuitive set up.  
Virtual Server  
Internet users can set up and access servers (such as WWW, and FTP)  
through the Virtual Server mapping function of the PalmRouter Elite.  
Security  
The PalmRouter Elite provides firewall-like security to prevent unautho-  
rized Internet users from accessing internal files. It can also filter out Internet  
requests from certain nodes on a local network - a feature that is ideal for  
administrative purposes.

EASY INSTALLATION  
Hardware Installation  
Modem Connection  
Connect one end of an RS-232 serial cable to the modem/ISDN TA.  
Connect the other end to either of the two DB-9 serial ports found on the back  
of the PalmRouter Elite.  
If you are connecting a modem designed for Macintosh use to the  
PalmRouter Elite's serial ports, the Mini-Din 8 to RS-232 DB-9 adapter (con-  
tained in the package with the PalmRouter Elite) should be used.  
Note:If you want to reset the modem and you are using the Mini Din-8 to  
RS-232 Adapter (to connect a modem designed for Macs), please  
wait for 10 seconds after turning the power off in order to let the  
PalmRouter Elite detect the disconnection.  
5
 
The PalmRouter Elite can support up to two modem connections simulta-  
neously. The two serial ports labeled "SERIAL 1" and "SERIAL 2" can func-  
tion as dial-out connections. To do so:  
1) Connect the phone line to the modem/ISDN TA.  
2) Connect the power adapter to the modem/ISDN TA and keep the  
power off until all hardware installation procedures are complete.  
Connecting the PalmRouter Elite to Your Network Environment  
Use standard twisted-pair Ethernet cables with RJ-45 connectors to con-  
nect computers or other Ethernet devices to the RJ-45 ports of the PalmRouter  
Elite.  
You can connect computers to any one of eight RJ-45 ports on the rear  
panel of the PalmRouter Elite. But if you intend to connect the PalmRouter  
Elite to another hub, we advise that you keep port No.8 free because this is  
the only port that can be used to uplink the PalmRouter Elite to another hub.  
Uplinking can be done by setting the DIP Switch beside the port from  
"straight" to "crossover" mode.  
Plug the power adapter of the PalmRouter Elite into an AC power outlet,  
then plug the power adapter output cable into the power connector on the rear  
panel of the unit. The Power LED on the front panel should be lit immediate-  
ly.

Easy Installation  
Software Configuration  
TCP/IP Network Configuration of Clients  
After installing the PalmRouter Elite hardware, the PalmRouter Elite  
needs to be configured through a Web browser (such as Netscape Navigator,  
Netscape Communicator, or Microsoft Internet Explorer). The computer that  
will manage the PalmRouter Elite must have its TCP/IP settings configured  
correctly. All other computers receiving Internet access through the  
PalmRouter Elite must also have their TCP/IP settings configured correctly.  
The PalmRouter Elite's default IP address is "192.168.1.1". In order to  
connect the PalmRouter Elite, the computer designated for managing clients  
must be on the same subnet as the PalmRouter Elite. Consequently, IP  
addresses ranging from "192.168.1.2" to "192.168.1.252" are legal for clients  
to use. IP addresses from "192.168.1.253" to "192.168.1.255" are reserved for  
system use and network broadcasts.  
The PalmRouter Elite can support both Windows and Macintosh  
platforms. Please follow the proceeding steps to configure the Windows and  
Macintosh TCP/IP settings.  
7
 
Windows 95 TCP/IP Configuration  
1. Double click the Control Panel icon in My Computer folder.  
2. From the Control Panel, double click on the Network icon to show the  
installed network interface card and network protocol on the  
Configuration list. Double click the TCP/IP protocol on the list. If  
TCP/IP does not appear on the list, you must install the TCP/IP proto-  
col first. For the clients with TCP/IP already installed skip to step 4.  
3. Keep your copy of Windows 95/98 CD-ROM on hand and on the  
Configuration list of the Network window click the Add... button. In  
the window that appears, double click Protocol, then on the Select  
Network Protocol window choose Microsoft on the Manufacturers list  
and select TCP/IP on the right side of the list. Follow the instructions  
that appear on the monitor to complete the installation.  
8
 
Easy Installation  
4. After double clicking the installed TCP/IP protocol, the TCP/IP proper-  
ties window appears. Click IP Address and select the Obtain IP  
address automatically item. (This is a more convenient way to set up  
the TCP/IP configuration of clients that relies on the built-in DHCP  
server of the PalmRouter Elite). The Gateway and DNS Configuration  
settings can also be ignored because the PalmRouter Elite will config-  
ure them automatically.  
9
 
5. If there is already a DHCP server on the network, or if you  
prefer not to use the PalmRouter Elite's DHCP function, you can still  
set up the TCP/IP configuration manually. Remember, the IP address  
you specify must be on the same subnet as the PalmRouter Elite's IP  
address to avoid IP address conflicts. Set up the Subnet Mask as  
Ó255.255.255.0Ó and specify the DNS address with the value that your  
ISP provides. The Gateway IP address must be the same as the  
PalmRouter Elite's IP address (the default IP address is "192.168.1.1").  
6. After specifying the settings of TCP/IP click ÒOKÓ and restart  
Windows to let the settings take effect.

Easy Installation  
Mac OS TCP/IP Configuration  
1. Open the TCP/IP control panel.  
2. In Connect via field, select Ethernet if you intend to use the built-in  
Ethernet interface on mainboard, or select an alternate network driver  
if you have a third party Ethernet adapter installed in your computer.  
3. In the Configure pull-down menu that appears, select Using DHCP  
Server to allow the built-in DHCP server of the PalmRouter Elite to  
assign an IP address and other TCP/IP configuration information to the  
client automatically. Do this for each client that needs Internet access  
through the PalmRouter Elite  
11  
 
4. If there is already a DHCP server on the network, or if you prefer not  
to use the PalmRouter Elite's DHCP function, you can select Manually  
to specify an IP address and other TCP/IP configuration information  
yourself. Remember the IP address you specify must be on the same  
subnet as the PalmRouter Elite's IP address to avoid IP address con-  
flicts on your network. Set up the Subnet Mask as Ó255.255.255.0Ó  
and the Router address the same as PalmRouter Elite's IP address. Set  
up the DNS address with the value that your ISP provides.  
12  
 
Easy Installation  
5. Close the TCP/IP window and save the changes.  
Setting Up the PalmRouter Elite through a Web Browser  
1. After performing the TCP/IP configuration of the computer that will  
manage the PalmRouter Elite, start the Web browser to connect the  
PalmRouter Elite. (Netscape Communicator 4.0, Internet Explorer 4.0  
or above are necessary for configuring the PalmRouter Elite. Other  
clients are not subject to this restriction).  
2. Type the PalmRouter Elite's IP address in the Web site address area  
(Ò192.168.1.1Ó as the default setting) and press ENTER. The  
Username and Password Required window will pop up. Leave the User  
Name blank and enter the Password ÓadminÓ, which is the default  
password of the PalmRouter Elite. You can change the password  
through a Web management page later. Click ÓOKÓ to enter the Web  
management page.  
13  
 
3. The OnePage Setup window will pop up. Select the applicable ISP  
name from the pull-down list. The default setting is Standard PPP.  
For example, if you use CompuServe on-line service to access the  
Internet, then select CompuServe.  
Note: America Online (AOL) doesn't support PPP dial-up connections.  
However, clients may use AOL through TCP/IP after an initial  
connection has been made through a PPP dial up account.

Easy Installation  
4. Fill in the ISPÕs phone number, DNS IP address, User ID and  
Password respectively. You can obtain this information from your  
ISP.  
Example:  
ISPÕs phone number: 444-555-6666  
DNS IP address: 222.162.134.232  
User ID: Macsense  
Password: xxxxxxx  
5. Leave the Intranet Settings as default, Gateway IP address  
Ó192.168.1.1Ó and Subnet Mask Ó255.255.255.0Ó, unless you need to  
make modifications to fit your network environment.  
6. Examine all values before clicking Save and leaving the Web manage-  
ment page. In most cases you can connect to the Internet with these  
settings completed. By launching a Web browser, e-mail application or  
other program, the PalmRouter Elite will proceed to dial-up.  
7. If an error occurs during the dial-up process, or if ISDN TAs will be  
used for dialing up to an ISP, you should specify the modem settings  
manually of the Modem Setting page. Please refer to the Modem  
Setting section in the "Advanced Configuration" chapter.  
15  
 
Advanced Configuration  
ADVANCED CONFIGURATION  
Please refer to the previous chapter on how to enter the Web Management  
page of the PalmRouter Elite. The Advanced Menu contains six submenus  
including Intranet Setting, Modem1 Setting, Modem2 Setting, Device Admin,  
Status Monitor, and Support.  
Intranet Setting  
Click Intranet Setting in the Advanced menu. There are three parts you  
will need to set under this page: IP Setting, Filter,and Virtual Server.  
IP Setting  
The Gateway IP Address and Subnet Mask of the PalmRouter Elite can  
be specified in this part. You can also choose if you would like to use the  
built-in DHCP server on the Dynamic IP Address setting. Set the Starting IP  
Address and Number of Users that the built-in DHCP server will assign when  
the DHCP function is enabled. The default setting for Starting IP Address is  
Ó192.168.1.100Ó. You can specify your own Starting IP Address, but remem-  
ber to make sure the IP address you specify is on the same subnet as the  
PalmRouter Elite.  
16  
 
Advanced configuration  
Filter  
In this part of the Intranet Setting menu, the IP Address Filter prevents  
up to 5 local network clients from accessing certain services on the Internet  
via the PalmRouter Elite. The specific types of Internet services to be filtered  
are based on the TCP port numbers which these services use for communica-  
tion.  
Some well-known TCP port numbers are listed below:  
Port number  
Service name  
FTP  
21  
23  
Telnet  
25  
SMTP  
DNS  
53  
70  
Gopher  
HTTP  
80  
110  
161  
POP3  
SNMP  
Up to 5 TCP ports can be specified on the Filtered Private Ports setting.  
17  
 
Advanced Configuration  
Virtual Server  
It is possible to set up a server such as a Web or FTP server on your net-  
work for Internet users to access. Internet users simply need to enter the IP  
address that has been assigned to your dial-up connection to get access to  
LAN servers. The PalmRouter Elite will redirect the request of the Internet  
user to the specified IP address of the TCP port request.  
Note: It will be much more convenient to have a fixed address from your  
ISP. Failure to do so will result in being assigned a different IP  
address every time a dial-up connection is made to the ISP.  
For example, if you set up the TCP port 80 (HTTP: Hypertext Transfer  
Protocol) to be redirected to IP address"192.168.1.2" on the Virtual Server  
setting, the request from the Internet user via HTTP protocol (i.e. acquire Web  
page from browser) will be transferred through the PalmRouter Elite to the  
computer with IP address "192.168.1.2" on your local network.  
18  
 
Advanced configuration  
Modem1 Setting  
Modem1 is the modem connected to the Serial1 port of the PalmRouter  
Elite. There are three parts to set up in this page.  
General  
Select the Line Type and the Baud Rate from the pull-down menu. The  
selection in the Line Type field includes Dial-up, Leased Line and ISDN. It  
is suggested that the Baud Rate should be about four times the maximum  
speed of your modem. In the ISP Name pull-down menu, select Standard  
PPP for common ISPs or select CompuServe for CompuServe online ser-  
vice. Enter the necessary ISP and Authentication information.  
19  
 
Advanced Configuration  
If your ISP account needs a Login Script for authentication, click the  
Script button and a window below will pop up. Enter the necessary script file  
to connect to the ISP. The following is a sample script file with the proper  
syntax and the meaning of the command.  
20  
 
Advanced configuration  
Command  
~~  
Description  
Wait for two seconds before executing the next script  
line. The number of "~" stands for the time of seconds.  
"ogin:"  
The double quotes stands for sending/receiving the mes-  
sage. The 'ogin:' is part of 'login:'. To avoid mistakes  
such as lowercase/uppercase error on the beginning let-  
ter "L". Use "ogin:" as criteria to verify that the ISP is  
sending login message.  
"Neil"  
After receiving the login requirement from the ISP, you  
can enter your login name 'Neil' within double quotes to  
send the message. Please note that the login name is  
provided by ISP.  
~~"word"  
'word' is part of 'password'. After sending out the login  
user name, you may wait two seconds for the ISP to ask  
for your password.  
"a5831010"  
After receiving the inquiry from your ISP, please enter  
your password within double quotes to send the mes-  
sage.  
IP Address  
If you can get a fixed IP address from your ISP, you can enter the fixed  
IP address here. The fixed IP address would be very useful for an Internet  
user to get access to the resources on your local network.  
Enter the DNS (Domain Name Server) IP address obtained from your ISP  
on the DNS setting. Up to three DNS IP addresses can be set.  
21  
 
Advanced Configuration  
Advanced  
This page describes how to set up the initial string for the modem con-  
nected to the SERIAL 1 port of the PalmRouter Elite. You can use the pre-  
defined setting on the pull-down list if your modem appears on the list, or set  
up the modem initial string manually. Please refer to the user's manual of your  
modem for the initial string configuration.  
Note: Unlike most modems, ISDN initial strings vary between different  
ISDN TAs and there is no "Standard ISDN TA" initial string. If your  
ISDN TA is not listed in the modem selection list, you must set up the  
ISDN TA initial string by yourself. The initial string should be listed in  
your ISDN TA user's manual. There are probably many initial strings  
listed for your ISDN TA. The one you are looking for is Asyn-to-Sync  
PPP (Asynchronous to Synchronous PPP). You can enter this initial  
string if only one channel of you ISDN TA will be used. If you would  
like to bundle both channels of your ISDN TA together, you should  
use the initial string for Multilink-PPP instead.  
22  
 
Advanced configuration  
You should also verify whether your ISDN TA supports the Dial-up string  
ATDT. Most ISDN TAs support ATDT but a small portion of ISDN TAs sup-  
port ATD or ATDI.  
Please also note that to bundle the two channels of ISDN TA together,  
you must enter the two phone numbers in the Telephone Number field of the  
Modem Setting menu.  
You can disable the Dial on Demand function on this page. The default  
setting is ÒenableÓ and it is recommended. On this page, you can specify the  
amount of idle time that passes in network activity before the PalmRouter  
Elite disconnects.  
Dynamic Bandwidth Allocation can be selected to be on or off. If  
Bandwidth Allocation is enabled, the threshold to activate modem 2 should be  
specified in the percentage of maximum traffic through modem 1.  
23  
 
Advanced Configuration  
Modem2 Setting  
The Modem2 Setting page contains the functions needed to set up the  
modem connected to Serial2 port of the PalmRouter Elite.  
Settings of Modem2 are identical to Modem1. Please refer to Modem1  
Settings for details.  
Device Admin  
This page is designed to show the firmware version and MAC address of  
this PalmRouter Elite. You may change the password or reset the device here.  
Selecting "Yes" to the Factory defaults will clear all the settings previously  
configured and return to the default configurations.  
24  
 
Advanced configuration  
Status Monitor  
This page provides information on the working status of the PalmRouter  
Elite.

Troubleshooting  
TROUBLESHOOTING  
This chapter provides solutions to problems that may occur during instal-  
lation and operation of the MIH-108 PalmRouter Elite.  
1. The Link LED is off.  
¥ Check all connectors to make sure they are well  
connected.  
2. The collision LED is always lit.  
¥ Make sure that the 10BASE-T cable does not exceed its specified  
maximum length (100-meters).  
¥ Check all connectors to make sure that they are secure.  
¥ Use Category 5 cables. Each wire should have a solid  
connector.  
3. Modem is not able to dial out.  
¥ Make sure all of the physical connections are secure and the  
modem is powered on.  
¥ Make sure a working phone line is connected to the modem.  
¥ The ISP's phone number was incorrectly entered.  
¥ The phone number may need a prefix digit such as "0," to get an  
outside line. The comma stands for the connection waiting time.  
¥ Try adjusting the Baud Rate. (Instructions are on the General page  
of the Modem 1 Setting section).  
4. Modem can dial out, but won't connect to the ISP.  
¥ Check the initial string set up. Be sure to power off and power on  
the modem after changing the initial string.

APPENDIX C GLOSSARY  
DHCP  
DHCP is a protocol for automatic IP configuration. Client side computer  
can get one IP from DHCP server automatically. Using DHCP can save the  
effort of setting IP for every LAN computers.  
Dial-up Access  
Refers to connecting a device to a network via a modem and a public  
telephone network. Dial-up access is really just like a phone connection,  
except that the parties at the two ends are computer devices rather than peo-  
ple. Because dial-up access uses normal telephone lines, the quality of the  
connection is not always good and data transfer rates are limited, but new  
technologies such as ISDN provide faster speed.  
An alternative way to connect two computers is through a leased line,  
which is a permanent connection between two devices. Leased lines provide  
faster throughput and better quality connections, but also more expensive.  
Domain Name  
A name that identifies one or more IP addresses. For example, the domain  
name "microsoft.com" represents many IP addresses. Domain names are used  
in URLs to identify particular Web pages. For example, in the URL  
pcwebopedia.com.  
IEEE  
Abbreviation of Institute of Electrical and Electronics Engineers, pro-  
nounced "I-triple-E". Founded in 1884, the IEEE is an organization composed  
of engineers, scientists, and students. The IEEE is best known for developing  
standards for the computer and electronics industry. In particular, the IEEE  
802 standards for local-area networks are widely adopted.

Internet  
A global network connecting millions computers. As of 1998, the Internet  
has more than 100 million users worldwide, and that number is growing  
rapidly. More than 100 countries are linked into exchanges of data, news and  
opinions.  
IP Address  
An identifier for a computer or device on a TCP/IP network. Networks  
using the TCP/IP protocol route messages based on the IP address of the des-  
tination. The format of an IP address is a 32-bit numeric address written as  
four numbers separated by periods. Each number's range is from 0 to 255. For  
example, 1.160.10.240 could be a legal IP address.  
ISDN  
Abbreviation of integrated services digital network, an international com-  
munications standard for sending voice, video, and data over digital telephone  
lines. ISDN requires special metal wires and supports data transfer rates up to  
64 Kbps (64,000 bits per second).  
ISP  
Short for Internet Service Provider, a company that provides access to the  
Internet. For a monthly fee, the service provider gives you a software pack-  
age, username, password and access phone number. Equipped with a modem,  
you can then log on to the Internet and browse the World Wide Web and  
USENET, and send and receive e-mail.  
Local Area Network (LAN)  
A computer network that spans a relatively small area. Most LANs are  
confined to a single building or group of buildings. However, one LAN can  
be connected to other LANs over any distance via telephone lines and radio  
waves. A system of LANs connected in this way is called a wide-area net-  
work (WAN)

Glossary  
MAC Address  
Short for Media Access Control address, a hardware address that unique-  
ly identifies each node of a network. In IEEE 802 networks, the Data Link  
Control (DLC) layer of the OSI Reference Model is divided into two sublay-  
ers: the Logical Link Control (LLC) layer and the Media Access Control  
(MAC) layer. The MAC layer communicates directly with the network media.  
Consequently, each different type of network media requires a different MAC  
layer.  
PPP  
PPP (Point-to-Point protocol) is a communication protocol for transmit-  
ting information over analog telephone lines. A PPP account is a dial-up  
account used to access the Internet. It is a dial-up account that actually calls  
another computer to gain Internet access.  
PAP/CHAP ISP  
PAP stands for Password Authentication Protocol. CHAP means  
Challenge Handshake Authentication Protocol. Most ISPs use one or the other  
for user authentication. If your ISP does not support either of these two proto-  
cols, contact the ISP for login script. You have to key in the login script on  
the PalmRouter Elite.  
TCP/IP  
Acronym for Transmission Control Protocol/Internet Protocol. TCP/IP is  
a program consisting of two layers of protocols or languages used to control  
the flow of information over the Internet. The Transmission Control Protocol  
aids in packaging large files of information into smaller packets of data that  
are ready for transport. The second layer Internet Protocol controls the  
addressing system, in a sense determining where the data packets are sent.
