Hi, im subscribed to the FreeBSD Security List but for some reason
i cant post in the list and i need to do a query... can you put it
on the list for me please? (Thanks a lot)
If you want, this is the question:
Subject: About Natd and ipfw...
Hello, i want to do ip masquerade and transparent proxy for an
intranet using a FreeBSD like a gateway. Everything in the same
machine.
I mean, the server FreeBSD will do all the interface betewen
Internet and the computers of my intranet.
We have a router Cisco, and it is configured for sending all
request of the clients to the server FreeBSD.
In this moment, masquerading is working good (it is for irc,
telnet, etc)... the problem is that we want to do transparent proxy,
using squid on the same server (The FreeBSD).
Whats going on?... well, the server have only one network card,
and we dont know what rules use to make it work like a transparent
proxy WITHOUT masquerading the http requests from the computers of the
intranet. We tried several rules, but when we redirect packets to the
port 8080 in the same machine, all of them are masqueraded and the
squid dont get nothing.
The point is, with the same network interface is possible that
ip masquerade and transparente proxy (with squid in the same
machine) works ???
Thanks...
