FreeBSD Firewall
What is the firewall that FreeBSD is using?
I'm planned to switch from OpenBSD to FreeBSD firewall with minimal configuration such as PPPOE DHCP DNS - unbound Snort Squid MAC enforcement. Operating system lock down No web server or database server or any others. Thanks. |

That information can be easily found in the the FreeBSD handbook.

FreeBSD has 3 firewalls available: IPFW, ipf, and pf.
pf is different from OpenBSD's pf and was rewritten for SMP support and uses the older syntax (pre-4.7 I believe). ipf is maintained by one or two people I believe but if memory recalls there was talk of removing it since it was not maintained, until someone stepped up. ipfw is the firewall that is FreeBSD developed. There is some discussion with the state of pf in FreeBSD which can be followed here Future of pf firewall in FreeBSD |

I am sure SmallWall people (some old m0n0wall users) are happy too. http://smallwall.org/ Quote:
It should be also mentioned that there is another separate active fork of IPFW developed by a DragonFly BSD guy which goes under the name IPFW2. |
