I have a supermicro H8DME-2 mobo from tamsolutions. Currently my nics are configured as follows:

 

eth0   Link encap:Ethernet  HWaddr 00:30:48:c5:e3:c8
          inet addr:192.168.2.4  Bcast:192.168.2.255  Mask:255.255.255.0

when i ping from eth1 to eth0 i get:

root@Icarus:/# ping -I eth1 192.168.2.4
PING 192.168.2.4 (192.168.2.4) from 192.168.2.5 eth1: 56(84) bytes of data.

however if i try to ping WAN i get

root@Icarus:/# ping -I eth1 google.com
PING google.com (74.125.224.226) from 192.168.2.5 eth1: 56(84) bytes of data.

For some reason i cannot ping the WAN from eth1 (eth0 is perfect)

 

Here is my route table as well.

root@Icarus:/# route -n

Appears to work but not ping?

There is not gateway defined for eth1.
