I have an IBM RS/6000 server running AIX 4.3. We have changed just changed
our network addresses from a 10.3.6.0 network with a mask of 255.255.240.0
and gateway of 10.3.6.1 to an IP of 10.x.42.0 network with a mask of
255.255.224.0 and a gateway of 10.x.32.1. I cannot ping outside of this
network meaning 10.x.0.x or 10.x.64.x. I have made the changes in smit
tcp/ip
an looked at the static routes. I don't beleive I should need to out
additional static routes in. The router/gateway should forward this. Or am
I wrong.

Please help!

I have 86 people that will need to use this server on Monday morning.

Any thoughts?

Have you checked that the changed of default route actually worked? I
have seen smit cheerfully say "OK" when asked to change a default route
when it has in fact failed.

Can you ping the router?

If you continue to have trouble, post the output of netstat -rn.

Check if you have many default routes ?
lsattr -El inet0

if so, correct this with smit, and flush routing table
