Hey everyone... I'm trying to setup the following, and I'm failing miserably. Internal network -[ed0]- FreeBSD (2.2.5) box -[ex0]- public IP 192.168.0.0/24 1.2.3.4 - FreeBSD box blocks all incoming connections, except on TCP port 25 Here's what I have. Note that the NAT for internal machines accessing the 'net works nicely. However, I can't figure out how to allow tcp port 25 into the box on it's public interface [ex0]. o FreeBSD box is assigned 192.168.0.1 on the ed0 interface, and 1.2.3.4 on the ex0 interface. o The following script is executed to initiate things: natd -log -redirect_address 192.168.0.0 0.0.0.0 -n ex0 -u ipfw -f flush ipfw add divert natd all from any to any ipfw add pass all from any to any Any help would be GREATLY appreciated!!!
