>Description:
Please find attached the FreeBSD port of ftp-proxy(8) from OpenBSD 4.0.

There is already an older version in the base system, which is from OpenBSD 3.7. This one was completely rewritten and now uses pf's anchor facility.

As it depends on libevent, I for one was unable to patch the version in the base system without major changes.

A website tracking versions can be found at http://www.chrissicool.net/projects/ftp-proxy/

# This is a shell archive.  Save it in a file, remove anything before
# this line, and then unpack it by entering "sh file".  Note, it may
# create directories; files and directories will be owned by you and

X===================================================================
XTo make use of the proxy, pf.conf(5) needs the following rules. All
Xanchors are mandatory.  Adjust the rules as needed.
X
XIn the NAT section:
X
X  nat-anchor "ftp-proxy/*"
X  rdr-anchor "ftp-proxy/*"
X  rdr pass on $int_if proto tcp from $lan to any port 21 -> \
X      127.0.0.1 port 8021
X
XIn the rule section:
X
X  anchor "ftp-proxy/*"
X  pass out proto tcp from $proxy to any port 21 keep state
X
XAdd the following line to your /etc/rc.conf to enable the proxy on
Xstartup:
X
X  ftpproxy_enable="YES"
X
XPlease consult the man page ftp-proxy(8) for more information.
