Try pinging the public address from another non-gateway system
on your LAN. If this other system is using the same default gateway
as the RS/6000 and it works, then the problem is RS/6000 related.
If pinging the public address from this other non-gateway system
does not work, then problem is probably with W2K Gateway system
or router. At this point, try pinging this public address from the W2k
Gateway system and work your way the your WAN access device.

... and looks you have a firewall on some place, cos you got a private
Internet number (10.0.0.x). Maybe your W2K or firewall could use some NAT
to permit external access.

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?
