NAT does translation between private and public IP's, so you can have more machines connected to the Internet than you have available public IP's. It's also more secure, to have LAN machines hidden behind NAT box. Bridge only forwards packets from one network to another. It can't be reached trough the net as it does not work with IP. Machines behind bridge are in the same network as ones in front, no translation happens here. > i currentlly only have one int_lan, but plan on haveing 2 int_lan's > and a DMZ once the hardware becomes available. Use NAT to connect LANs and redirection for DMZ. Damir
