We have a firewall on our large campus network. QuickTime Conferencing (QTC) works fine inside the firewall, but when trying to go through it, the TCP/IP port appears to be selected at random. Is there a way to specify the port so we can configure the firewall to let QTC work?
QTC will not work across firewalls, but the router can be reconfigured with the proper "well known port number" 458 (Conference) & 545 (Broadcast) to accommodate QTC packets. Unsecured range is 6000-6255, but it may change.
