(Yes - to all non-south-africans - that means it's working..)

As someone else said: Squid only does HTTP, FTP(in http mode), gopher,
and HTTPS.

You need to check out something like 'plug-gw' (should come with

through to the inside... If you want to do ICMP it's a different story...
if that's the case you may as well turn routing on on the unix box...
