Re: Transparent proxy with FreeBSD

there is an option to support transparent proxying in -current.
it is part of the ipfw code..

Peter wemm has a 2.2.x relative version of the code..

you do,
ipfw add 2 fwd 127.0.0.1,3128 tcp from any to any 80 recv in lan0 out wan0

where lan0 and wan0 probably ed0 and tun0 or similar.

your proxy server should be listenning on 3128

all requests being routed through that box to (anything) port 80
will be diverted to the local proxy listenning on 3128.

requests from the local box (e.g. from the proxy server (duh) will not
be changed.).

there are some changes that can be made to squid to make it work a BIT
better.
