I hate to tell you this, but an Appliance can block outgoing calls to
ports 1000-5300 and to port 80 on any IP too. What kind of firewall
appliances are you using that don't block outbound based on user defined
rules?

Oh, and blocking outbound calls to port 1000-5300 can break many normal
connections.
