I am seeing the following blocked traffic when trying vdeo conferencing between two site. Both are behind Checkpoint NGX HFA_02 running on Nokia IP 350's with IPSO 4.0.

Any ideas what I can configure to allow this traffic?

This is "fixed" in HFA_3, which should be released RSN. If you cannot wait, call support, I belive there is a hotfix available.

Due to numerous other small errors on that particular Nokia box, I am replacing it with a SPLAT platform this weekend and then rebuilding the Nokia from scratch. If the problem persists I'll look at the hot fix, although the video is not being blocked by an identical Nokia gateway at the other end.

After numerous suggestions from Nokia, Checkpoint and users goups, I was not able to determine why the H323 packets were being dropped by only one of our firewalls. But, I was able to by-pass the problem by enabling wire mode on the VPN connection between the two sites internal ports.

Video conferencing is now working.
