Because pound is running on my router, I was wondering if it is possible to
make pound totally transparent.
I would prefer this over the current situation because the logs on my router
are not kept after a powercycle.

I don't need to know immediately how to do this, but just want to know if it is
possible with too much effort. My MIPS-powered Asus-router is running Linux
(DD-WRT) with iptables.

Any info is welcome...

Transparent in what respect?  If pound is involved, its going to be 
visible at the IP level, since to your webserver it'll appear as if all 
the connections come from pound.  mod_rpaf is your friend here if you're 
using Apache on your backend.

If you wanted your packets to appear to come from the real "client's" ip 
(nevermind proxies for now) you're going to need some kind of 
kernel-level support.
