0.9.1 was successfully compiled under FreeBSD, however only TCP based
proxying works, forging TCP source addresses and UDP connection tracking
doesn't.

The core of Zorp is quite platform independent, but some features require
platform dependent functions, which are either not implemented under *BSD,
or we don't know how they can be used.

Works:
* redirection via ipfw or ipfilter, Zorp finds the original destination
(requires --enable-ipfilter configure option)

Doesn't work:
* setting the outgoing source IP address of TCP connections (required when
you want to send real client IPs to a server in your protected zone)
* intercept connections without REDIRECT rule (used by the FTP proxy when
the data channel is established)
