Our office intranet is located at office.mycompany.com. Inside the office, however, the DNS for 'office.mycompany.com' resolves to our EXTERNAL IP address, and since I have loopback disabled (for security), it barfs when trying to access the intranet.

So, I figured, hey-- I can install squidGuard, and create a rewrite rule to redirect them to the internal IP of the web server.

My rule looks something like this:

rew office {
s@^http://office.mycompany.com@http://192.168.10.10@i
s@^http://www.lycos.com@http://www.google.com@
}

I threw in the lycos->google rule just for testing.

I restart Squid, and the lycos->google rule works just fine, but I still get an error with the office rule above it... I get the standard Squid error page:

Is this just a simple permission problem in the squid.conf?

Another idea I had was to modify my bind server configuration--but alas, I don't have the time to learn how to configure bind (I tried before, and ugh, it was very painful)

Hmm... I think it has something to do with the fact that my firewall's name is "firewall.office.mycompany.com" ...

Because

rew office {
s@^http://www.lycos.com@http://192.168.10.10@
}

works just fine ...

The only thing that doesn't work is the name 'office.mycompany.com'...

Any ideas?

I want to do something almost exactly like what you have there.

Do you know of any documentation to do that? the squidguard site doesn't have any.
I'd like to understand it a bit before I simply copy, paste, and edit.

so.. it turned out to be just as easy as you wrote.

(I'm using it with apt-proxy to make sure there's no leakage of bandwidth)
