Do you have forwarding turned on? For some reason I had to issue a command
in a startup script to set forwarding to on. Check
/proc/net/ipv4/ip_forward (I'm not sure of the exact path, not by my machine
today) but there should be a 1 in that file. This will turn forwarding on
It always resets back to 0 each time I shut the machine down so I had to put
this command in the startup script:
echo "1" > /proc/net/ipv4/ip_forward (again not sure of exact path)

I don't mean to be such a newbie about this, but I haven't worked
with
routing before.
I added the ipchain provided. I can now ping the 128.129.110.253
from a
workstation on the 192.168.1.0 side, but I can't ping any machines
on the
actual 128.129.110.0 network.
Is there something else I am missing?
When I execute a 'route' or 'ipchains -L' command on the router box
it
takes a long time to execute.
>ipchains -A forward -p any -b -s 192.168.1.0/24 -d 128.129.110.0/24
-j
>ACCEPT
