The usual answer: Squid is a HTTP proxy. Not a layer-4-firewall.

The "classical" approach is to use a firewall to block all outgoing traffic
and only allow connections to the internet that go through a proxy. That's
what some "application layer firewalls" do, too. Every protocol needs a
certain proxy to work. Since Squid is not a peer2peer proxy that protocol
won't work unless it speaks HTTP.

Squid is not extensible to do anything else but HTTP proxying.
