-----BEGIN PGP SIGNED MESSAGE----- Thanks to everyone for your answers. To clarify, the question was meant for outbound http/https proxy only without caching files. From the answers I received I can see no reason that the Proxy port couldn't be 80 in this case with the Proxy Servers only having access through the firewall.
