Firewall and NAT Issues
Note: This issue is resolved in ConferenceXP 5.0
Some feedback from Bob Riddle:
I've also given up on using CXP at the University of Michigan Medical School due to the inabaility of the Reflector to support clients sitting behind firewalls on NAT'd networks. The Reflector sets up the multicast tunnel using TCP but streams the CXP content using UDP - which leaves the firewall/NAT server without a clue as to where to deliver the UDP traffic.
Suggestions: either use UDP to setup the multicast tunnel to the Reflector or use TCP to deliver the content to the client from the reflector.
