I have two realtek 8139B ethernet cards mounted on Linux SuSE 7.3 server.

It seems that
eth0 (INTERNET) it's working...
eth1(LAN) it's working...

but i have no ping to my LAN
only the first pci slot on my mainboard where is connected the eth0 card it's functioning. All the other one don't want to send and receive packages.

SuSE it's viewing the two of ethernet cards.
ifconfig look like that:

Does anyone can help me finding a solution?

Are you using DHCP ?
Make sure all the computers on the LAN are obtaining different IP addresses.

Take a look at your routing table, type: route -n

Is your firewall blocking icmp packets ? iptables -L

Can the computers on your LAN ping each other and can they ping the server ?
