[Luna] Router help

[Len Bright]

Hello,
Is there anyone on this list who is an expert at setting up a Linux router?  
I have been attempting to set up an internal router/firewall using Suse 10.1 and as far as I
can tell I have all of the proper steps in place. Each network card is configured for internal and external IP addresses respectively, IP forwarding is enabled, etc. I run into some trouble when setting up routing with route -add.  I am using iptables to setup routing and masquerading. I am new to Suse having used Fedora before and an annoying thing I have found about Suse is that the firewall is obscured behing Yast and seems rather Windowsian from the standpoint that I can't seem to get into the files I need to make this work.  This becomes obvious when after I modify iptables for routing the Yast firewall complains that there is another firewall running.  I suppose I should just disable the Yast firewall. I am half tempted to reinstall Fedora.

I will spare everyone the details of the steps I have taken to setup routing unless someone is interested in knowing what I have done.  One item that sort of complicates
things is that I am attempting to setup routing a couple layers deep. What I mean by that
is I already have a router behind the DSL modem.  Any help you guys have to offer by
way of documentation, how-tos on Linux routing would be much appreciated. Thanks.

-Len
