Re: [squid-users] firewall and squid

I'm doing this on my home LAN but purely because I don't have the cash
(pun?) to have seperate computers for the firewall and cache. Still,
there's nothing stopping you having a firewall in more than one place so you
could run Squid from the DMZ but still have the squid box running it's own
firewall to make sure everything is closed off other than say port 3128 so
the only vulnerability on that box is likely to be Squid itself.

Still, my firewall is set up only to accept incoming connections that the
LAN has initiated,so if someone port scans me they see only the ports I need
to have open (eg http and smtp). Works quite well really I reckon.
