My main question is if the cisco router, which is broadcasting to the
198.30.16.xxx network, with a gateway of 198.30.16.2 is interfearing with
my want to be routing.

I was hoping someone can provide me with a little insight, here is my
layout.

I am running Linux kernel 2.0.32

I have two networks: 198.30.4.xxx
198.30.16.xxx

198.30.4.2
/---------------\ /--------------\ VIRTUAL GATEWAY /-----------\
| INTERNET |-------| CISCO ROUTER |===================|198.30.16.2|
\--------------/ \-------------/ \----------/
| |
| |
|/----198.30.4.4 |
/--------------\ 198.30.16.5 -
| LINUX BOX | 198.30.16.254
\--------------/ NETWORK
|\----198.30.16.1
|
HUBS
|
/--------------\
| SERVER |
| |
| 198.30.16.3 |
\-------------/

I have the folloing for the routing table.

198.30.4.0 netmask 255.255.255.0 eth0
198.30.16.0 netmask 255.255.255.0 eth1
gateway 198.30.4.2 eth0

I have IP enabled, and this is what I get. The server can ping
198.30.16.1 and 198.30.4.4, but can not ping 198.30.4.2 (the router).
The network can not ping 198.30.16.1 (the second NIC).

The linux box can only ping 198.30.16.1 and 198.30.16.3, the internet and
the
198.30.4.xxx range, but no other mahine on the 198.30.16.xxx network.

Have you experienced this??? Any help wpuld be greatly appreciated, I'm
loosing my hair ;->
