I reccomend just using 3 NIC interfaces. run 2 of em in bridged mode, e.g. my home network is protected by a freebsd box running 4 NICs, 1 management(inside internal firewall), NICs 2 and 3 are bridging, NIC 2 is the firewall, NIC 3 is snort, NIC 4 is not being used. this way since all traffic goes accross 2 interfaces I can run snort on the "internal" one so it has no chance of detecting what is dropped on the "external" one. then behind that machine I have another machine doing the NAT. works great. nate To Unsubscribe: send mail to [EMAIL PROTECTED] with "unsubscribe freebsd-questions" in the body of the message
