If I have both nic's connected to the switch I can ping 192.168.1.1 and 192.168.1.3 and 192.168.1.4 If I have only em0 connected I can ping 192.168.1.1 and 192.168.1.3 If I have only em1 connected I can ping 192.168.1.3. What could the 2 onboard nic's be best used for. I was thinking that in the event on was to fail then the other would still be ok. Any ideas would help. Thanks, Ivan
