zorp and freebsd

[MEZEI Tamas]

Hi,

is there any way to do "transparent proxying" in FreeBSD? I'd be happy 
to have a fully functional Zorp server based on FreeBSD.

Transparent proxying is working on Linux via the TPROXY patch, but ipf 
rdr methods are not really the same. Is there any way to implement that 
transparent stuff in FreeBSD? Are there any "unofficial" modifications 
(don't slap me please ;)?

Thanks,

Tamas
