Pfsyncd

pfsync is a network interface that helps a number of computers running OpenBSD's pf (packet filter) keep their state tables the same. pfsync can send messages indicating changes, or listen for such changes. pfsync can be configured using ifconfig. pfsync can be used in conjunction with CARP to make sure a backup firewall has the same information as the main firewall.
