Hello list, I have an older openbsd 3.5 system that is running well just as a firewall NAT router, with 3 interfaces on it.
Behind (and protected by) this is another machine. This particular machine was in use as a shell box, running ssh, web and mail under FreeBSD. I have converted it to OpenBSD 4.0. It gets lots of mail, and it has about 30 users on it. It has one NIC. I want to use PF to control spam. Question is, the pf.conf seems to want 2 interfaces in order to do this.. Is it permissable to set int_if and ext_if to be the same (same IP) or should I clone the interface? or is there another way that I haven't thought of? cheers -- John
