About the MicroRouter 1220i
Congratulations on your purchase of the MicroRouter 1220i multiport
wide area router. The MicroRouter 1220i supports the IP and IPX
network protocols, with leased-line and/or dial-on-demand operation
using the PPP, Frame Relay and/or SMDS wide area protocols.
A Note About Firewalls
The MicroRouter 1220i can be configured to be a very effective packet
screening firewall. However, you must carefully set up your network
and add packet filters in order for it to be effective in this role.
THE SHIPPING CONFIGURATION IN YOUR MICROROUTER
1220i DOES NOT PROVIDE AUTOMATIC FIREWALL PROTEC-
TION. YOU MUST FIRST PROGRAM YOUR ROUTER TO WORK
IN THIS ROLE ON YOUR NETWORK.
v Note:Due to the nature of the IP protocol, IP packet filtering can
be quite complicated. If you are attempting to design and implement a
comprehensive set of filters, or an Internet Firewall, there are a number
of references you should consult. Two good starting points are:
Building Internet Firewalls, by Brent Chapman, O’Reilly and
Associates, 1995, and Firewalls and Internet Security: Repelling the
Wily Hacker, by William R. Cheswick and Steven M. Bellovin,
Addison-Wesley Publishing Company, 1994.
A Note About On-Demand Internetworking
The MicroRouter 1220i can be configured to provide cost effective
on-demand connections over a wide area communications link (typi-
cally a voice phone line, a switched 56 line, or an ISDN line). Your
network traffic and the configuration you place in the router will deter-
mine how often and for how long such a link is connected.

1220i DOES NOT PROVIDE AUTOMATIC ON-DEMAND INTER-
NETWORKING. YOU MUST FIRST PROGRAM YOUR ROUTER
TO WORK IN THIS ROLE ON YOUR NETWORK.

MicroRouter 1220i Installation Overview
This manual will help you install the MicroRouter 1220i to connect two
local Ethernets to 1 or 2 remote networks and/or remote PPP client
computers. These connections can be made to other Compatible
Systems routers, routers from other vendors, or PPP compliant dial-in
software packages running on a variety of computers. The wide-area
interfaces on the MicroRouter 1220i may be used to interconnect your
network with other corporate networks, and to make your network’s
resources available to dial-in clients.
In short, the installation steps are:
1. Install the MicroRouter hardware and connect it to one or more
line communication devices (including modems, 56K CSU/DSUs,
ISDN Terminal Adapters, and fractional or full T1 CSU/DSUs).
2. Select the management method you wish to use with the router. If
you want to use the CompatiView management software, you must
install the software on a Windows PC which is connected to your
network.
3. Configure the MicroRouter LAN and WAN parameters using the
management method you have chosen.
4. Connect the secondary WAN port’s RS-232 to an external line
communication device (including modems, 56K CSU/DSUs, and
ISDN Terminal Adapters).
The manual is divided into several sections that should provide you
with all the information you will need to use the MicroRouter 1220i on
your network. For the latest documentation on Compatible Systems
