Re: ip forwarding hp-ux 11i
maybe I miss the point, but I can't find a route to be forwarded ...
You start traceroute from the server (192.168.0.1 ?), from there to the router 192.168.0.40?) with "default 192.168.0.1 UG 0 lan0 0" - which leads back to the server ... nothing which could forward to 10.121.18.x
But maybe I'm totally wrong ;)

Re: ip forwarding hp-ux 11i
Trace the stations step by step ... first to 192.168.0.40, then 10.121.18.100, then the final step. Maybe this could provide you with the missing part of the puzzle ...

Re: ip forwarding hp-ux 11i
server default gateway: 10.121.18.254
workstation ip: 192.168.0.40
workstation default gateway: 192.168.0.1
from server:
ping 192.168.0.40 -> success
ping 10.121.18.254 -> success
from workstation:
ping 192.168.0.1 -> success
ping 10.121.18.100 -> success
ping/traceroute 10.121.18.254 -> failure

Solution10.121.18.254
What routes does that have? In particular, what's it's default route, and/or does it have a route for '192.168.0.0/255.255.255.0' pointing back to '192.168.0.40' ?
