OK guys, This is my first post so I apologize if I'm in the wrong here. I have been reading Googling and reading OpenBSD PF man pages for the past week trying to understand PF and get the perfect setup. I currently have a dual-home setup that works great according to the simple-home setup in the PF Guide. However, I want to use the third ethernet card in my machine to setup a DMZ. However, I'm having issues with routing and a multitude of other oddites. Does someone have a pf.conf for a triple homed setup where the internal and DMZ networks are both RFC1918 networks. All I want to allow in and out of the DMZ are web, dns, pops, imaps, and smtp. If there is a good 3-legged howto out there....I don't mind reading that. I'm just confused as to whether I need to use proxy arp, or bridging. Any help CERTAINLY appreciated.
Robert P.S. If you would like to see my current pf.conf file, email me directly and I'll include that.
