Mail Proxy SMTP/POP3

[ada...@telusplanet.net]

I need a way of making it so I check my mail through the proxy. I am using squid
for the normal web proxy. Can I setup squid to pass SMTP/POP3 requests on to
the mail server?

I am using squid 1.1.22-2.

IP-Maquerading is your friend if you can put it on the firewall. Check
the relevant How-to, is the most hassle free solution.

Is Masquerading = NAT? This is what it sounds like to me. I have read the
masquerade howto, but it didn't work! I will try it again though.

Masquerading != NAT (it is a little brother to the more general NAT)

NAT can do many-to-many address translation.

Masquerading can only do one-to-many address translation.
(i.e. hiding a private subnet behind a masquerading firewall makes the
whole subnet appear to the internet as if there is only one machine
using lots of high ports).

Relevant configuration info and ASCII art with the layout of the
network sure helps?

What went wrong you ask. Well, I configured masquerading just like the
howto says. IT DIDN'T WORK!!!!!!!!

The person writing the howto forgot to mention that you have to enable
routing! I found this out by accident when I found a neat little utility
called "linuxconf". I enabled routing, and now it works.

Does anyone know how to enable routing? I used linuxconf so I don't know
what it did!

Ok, I will answer my own question. I can enable routing by editing
/etc/sysconfig/network, and then either rebooting, or running
/etc/rc.d/init.d/network reload!

Enable routing by typing
echo 1 > /proc/sys/net/ipv4/ip_forward
( at least on 2.2.x kernels )
