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 do not want to redirect any traffic to the firewall itself: for IP
accounting or other reasons
- you want to pass traffic to multiple FTP servers behind a firewall

In general, ftpsesame is a good choice to run on a firewall in front of
multiple FTP servers, where no NAT is involved. ftp-proxy(8) is usually
the best choice when users behind NAT need to access FTP servers on the
Internet. In other situations it depends, sometimes they are useful
together.
