PIX 515/NetMeeting.

Unanswered Question

I want to be able to send and receive video using NetMeeting through my PIX 515 firewall. What do I need to do/what ports do I need to open to make this work? This should be a simple config, I don't want to keep anyone on the inside interface from sending or receiving via NetMeeting. I tried opening up ports 1720 and 1503, but still can't get it to work. Any ideas? Thanks!

Netmeeting uses H.323

Make sure you have

fixup protocol h323 1720

and add

conduit permit tcp any eq h323 any


Worked perfectly for us,

however H.323 uses TCP and UDP ports above 1024 and this config dynamically opens the ports based on the calls.

I was concerned about opening up those ports about 1024. Doesn't an organization open themselves up to a certain extent by enabling those ports so H.323 will work?
