Karl,
You should verify that IP-Forwarding is turned on for the W2K box.

I dont understand this. Is the w2k server acting as a router or not? Is
it connected to networks that your aix-box isnt? If not, why dont you
use the router directly?
Are you sure the w2k was your default-gateway when it worked (before
your reboot)?

Pro* I'm embarrassed to even ask but...
A client's AIX 4.3 system feeds into a Windows 2000 server which then
sends traffic to the router. All was well until my last reboot. After
reboot, I
discovered:
- a bad hostname I had experimented with had stuck so the hostname
needed to be changed
- the default gateway had not been recorded as a permanent setting
I have since restored these two pieces of information and all is well
except that it is not routing traffic properly. (Internal TCP/IP
traffic is working fine.) The W2K box lists as the default on my netstat
listing. I can ping the W2K box. But, though they resolve properly (ala
DNS), I cannot ping outside addresses. In doing a traceroute, it bombs
on the first hop.
What am I missing?
