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.

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.

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.

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.

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.

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.

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.
