pftabled
The pftabled daemon is a small helper to make your pf tables reachable from other hosts. You can add/delete/flush IP addresses to/from a remote table with a single UDP datagram. Sample client programs in C, Perl, PHP and Python are included. This is in heavy use distributing blocked IP addresses to other systems at an ISP environment.
