My redhat linux Enterprise AS3 server is haveing an odd problem i had to switch the server to a diffrent ip address on a completely diffrent subnet. The problem that i am haveing is that after switching the ip address my server no longer had access to the internet but the internet still has access to my server i have checked and rechecked my configs but to no avail i can get webpages and email through the box but i cannot access webpages or send email while on the box it won't even ping the gateway router but the gateway router can ping it. i am pulling my hair out on this one.

open a bash console as root and type:

route

When your box is connected in the way that it doesn't see the gateway. When you type that command, it may hang, note the part that it hangs on, and then paste the output into a browser here and let us know where it was going slow. It should go really fast (like an ls command)

it doesn't hang it ran as fast as a ls command.
here is ifconfig just in case you curious:

The Bond0 is bonding done between eth0 and eth1

eth2 is the internet side nic and the cause of all my headaches.
