That was exactly my problem with those error messages.
Now, I took out all 'route add -net' from my /etc/init.d/network file. I
don't get
the error message anymore. However, my linux box still doesn't work as
a router. So, I downgraded the kernel to 2.1.125.
Here is a simple diagram of my network:
Cable Modem -----eth1 Linux Box A eth0----- eth1Linux Box B eth0------ NT
WORKS
Linux Box A kernel 2.0.36 ipfwadm rules (no trouble)
Linux Box B kernel 2.1.125 doesn't allow packets through from NT WORKS to
Internet
That's my route table now on Linux Box B:

Any idea what else could be missing?
Thanks.
