Hi!

I would need some starting info about transparent proxying.

So, first I forward the packet, on port xx to 127.0.0.1:xxxx
the proxy get the packet, and it will see the destination ip
127.0.0.1, isn't it? So how can I find out the original
destination
ip address of the packet?

Like linux with iptables:
getsockopt(... SO_ORIGINAL_DST ...)

Or with ipfilter's natlookup_t structure.
(Long to insert here)

But how, with ipfw?

Any help (man/rtfm ;-) is appreciated,
Best regards,

Szabados Jozsef
ps.: sorry for my bad english ;-)
