I have ipcop and installed the 3rd nic, will be trying for the 4th later. I have the ip address of the 3rd nic as 192.168.6.1. So when I connect something to this nic do I give the unit an ip address, say192.168.4.50 or does this nic also do dhcp and give out ip addresses?? Same question to the 4th nic???? I have the lan nic doing dhcp, but didn't see any setting for the 3rd and 4th nics.
