Networking ssues post RH 7.3 to RH 9.0

Help!,

I recently upgraded from RH 7.3 to 9.0..and now networking was somehow
broken in the process.

Initially there was and error thrown in the boot messages by
xinetd...that was resolved and no error or warning messages are in
the logs on system start-up.

The problem is that even though every thing starts it is isolated from
the network

ifconfig reports the interface up and running, the route table should
the correct default route to the gateway.

The system responds to all request on LOCAL HOST (SMTP, HTTP, DNS)
but network request on ETH0 are un answered. Also PING fails to
reach the gateway or any other machine on the network.

Any suggestions for fixing this would be appreciated.

Sounds like you have the firewall active. I don't use RH, but I'm sure
thre's a GUI tool to monitor and configure it.

No the RH Security tool is set to no security and iptables -L results
in an empty rule set

are you using DHCP? If so, is eth0 obtaining IP address and such as it
should?

Can you perform network-related tasks when you disable the firewall
software:

[root]# service iptables stop

No the machine has static address but functions as the DHCP server to
the rest of the network

do you have _any_ evidence that the physical layer is intact. that its in
effect 'plugged in.' And no, I am not joking. How about the lights on
your hub/switch? Can you turn on DHCP and see if that works at least? Do
the lights on the NIC flash indicating data passing on the local node?
