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
|
||
|
|
|
||
|
|
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.
