Know any good firewall programs (preferably free, but not neccessarily free) that are more geared for server use? What I am interested in is something a bit hands on where I can really control what goes in and out of my server and I would like some real time anti virus features possibly... or atleast something where I can have a regular scan. I have tried zone alarm, but it is kind of lame and not geared for server use anyway. They try to make you by pro by not even blocking out the messanger service. I enabled to thing just to see if zone alarm blocked it and it did not. Jerks.
