Subject: Transparent proxying to all hosts/all ports
Date: Tue, 24 Jul 2007 23:40:44 +0200 [thread overview]
Message-ID: <46A671DC.9030004@rootsucks.com> (raw)
Hi ! (Please be kind with my poor English...)
Main goal: having ALL connections using Linux TCP/IP stack.
Is there a way to run a fully transparent UDP/TCP proxy on a Linux
gateway instead of "just" forwarding packets with Netfilter ?
What I would like to achieve is to intercept all outgoing connections
from hosts in the LAN and force Linux to act as a transparent proxy,
being the only one "talking" on Internet.
TPROXY (maybe REDIRECT ?) seems to be the right Target for the
interception part because SRC/DST host:port are not altered but, correct
me if I am wrong, it does only allow to forward packets to one host.
Is there a tool that could inspect incoming packets and, using the
Dst addr/Dst port, connect to the right remote host and tranfer only
application data ? (HTTP, SMTP, DNS, NTP, etc.)
Thanks !
Philippe
