[FW1] Video Conferencing over FW with NAT?

["Zeltser, Roman" <Roman.Zeltser@FW1-NOSPAMssa.gov>]

Hi gurus,

I would like to get your opinion about videoconferencing over FW. Please,
share your experience (positive and negative) after your projects. Which
products did you use, how did you configure the rules, NAT, interfaces, etc?
   We have several proposals that include the following:
1. CuSeeMe- Ports: 7648, 1720, 7503, 24032 and UDP (H323 and T120 standards)

2. IRIS- Ports: 4969, 4970 and UDP

3. iVisit- Ports: 9943, 9945, 56768 and UDP

4. NetMeeting- Ports: 389, 522, 1503, 1720, 1731 and Dynamic UDP (H323 and
T120 standards)

I have two concerns: must-have UDP and NAT (we MUST use it)

Any experience?
