And if so how can >I achieve this. I just did this on a consulting contract for a M&M client. We replaced a BSD/i machine with a FreeBSD machine. Mail server is a postfix MTA + Qpopper. DNS is BIND9.2 with 2 views. He has an ADSL line with one external ip, and his Netopia router NAT/PAT's one-to-many statically. Port 25 of the router outside is PATted to the FreeBSD's port 25, same for port 110/pop3, and port 80 for http service. Same for BIND on port 53, since his machine is master with 3 DNS's at his ISP as slaves. His inside is 192.168.1.0/24. So go read the router manual. btw, NAT/PAT alone has no security, so you'll need at least packet filtering in or behind the router to protect the LAN.
