ftpsesame helps the FTP protocol get through your pf firewall. It does
this by passively analysing FTP control connections and adding rules
into a pf anchor when an FTP data connection is about to commence.
You might want to try ftpsesame instead of ftp-proxy(8) from the OpenBSD
base system for the following reasons:
- it runs on "transparent" (no IP address) bridges
- you need packetfilter performance on all data connections
- you have to handle lots of simultaneous sessions
- you do not want to redirect any traffic to the firewall itself: for IP
accounting or other reasons
