Hi
Enable the "Socket Filtering" under Networking Options in your Kernel Settings.
And possibly "Network Device Emulation"
This should fix the problem.

What kind of Network cards you have ?
I am experiencing the same problem and thinking about a driver
problem.
In a IBM Netfinity 3000 (etherexpress pro 10/100 onboard) and
any others NIC inside, I see a strange problem. I will explain....
eth0 - 192.168.1.1
eth1 - 192.168.1.2
eth2 - 192.168.1.3
If I remove the network cable from eth1 and eth2, the machine
remains responding to ping - for an unknown reason.... eth0 assumes the
address of eth1 and eth2.
if I remove the network cable from eth0, but connect the cable in
eth1 or eth2, the machine stops responding on the network. All the
addresses stop responding....
The system is a RedHat 7.3 with Kernel 2.4.19 compiled from
sources....
Anybody have an Idea ? Is that normal because all the ip address
are in the same subnet ? Any idea of why the NICs stop responding if I
remove the cable of the onboard NIC ?
thx
Rodolfo
