Hello Everyone. I
hope you all can help me, I'm sure you can (it seems like a pretty simple
problem).
I am setting up a
Squid proxy server to run in transparent mode. To do this, I need to forward all
port 80 and 443 traffic to squids' port, 3128. Additionally, I would like all
other traffic on all other ports to forward on to the router.
I have found a
script to forward port 80 to squid (note: eth1 is my internal interface, eth0 is
external):
iptables -t nat -A
PREROUTING -i eth1 -p tcp --dport 80 -j REDIRECT --to-port
3128
I assume I can run
the same line for 443:
iptables -t nat -A PREROUTING
-i eth1 -p tcp --dport 443 -j REDIRECT --to-port
3128
However, what can I use to forward EVERYTHING that is
not port 80 out of the eth0 interface, to our router
(192.168.0.2)?
I know it has something to do with --dport ! 80, but I
can't figure it out.
Thanks for your help.
BTW, this is RedHat 72. if that makes any difference.
Linux kernel 2.4.9-31.
