Ok, I'm new to OpenBSD and pf, but I'm quickly getting the hang of it. Here's my setup:
AMD 2300 w/ 512mb DDR ram 512mb flash drive 5 10/100 network cards I have 4 networks right now, one of them is the internet. So let's call them, Inet, A, B,and C. Network C is the network with all mail/web/dns/etc servers on it. A and B are networks, I could really care less what traffic goes to them, and from them, going to/from the internet and each other. I want networks A and B to be able to only access the mail servers on ports 25/110/80/443, dns servers on port 53, webservers on ports 80/443, and a couple of other servers via ftp. Should be very simple, I setup some rules to allow all traffic from Inet going to A and B. I then allowed all traffic from A and B going to Inet to pass through. I then setup some holes on C, to allow those ports to those servers that I want open. I also allowed network C to access http/https/ftp/dns/mail outside of it's network. I have a "catch all" in the bottom of my script, to just block everything that doesn't fit into anything else. I enable it.. what happens.. I loose connectivity to all the networks. Nothing can see anything outside of their network. do a ping from the firewall, and you get: ping: sendto: No route to host ping: wrote 192.168.3.250 64 chars, ret=-1 Anyone have any ideas?
