Video Streaming over VPN

HI

I am trying to use Logitech HD video software to connect 2 sites. Both sites have good fast internet connections.

Both sites are connected by a hardware VPN using Netscreen 50 firewalls.

When I try to establish a video call from site A to site B the connection goes through and connects. Logitech forum suggest it uses the internet to establish the connection but the traffic then goes through the VPN.

Site B can see and hear site A clearly but site A can see and hear site B but with lots of delay, broken up voice etc before it disconnects.

I have tested this using our guest wireless so it uses only the internet and bypasses our LAN and VPN connection and it works like a dream.

I am assuming it is something with the traffic that passes through the VPN tunnel that is causing the problem at site A.

I have checked the policies and can see no way of changing anything.

I dont think it is blocking the traffic as we can see each other for a short time before it disconnects.

Does anyone have any ideas??

Thanks in advance

You may need to prirotize the traffic for this video stream.

Don't know Netscreen, but
check in A's VPN properties if there is a gateway belonging to B, causing a gateway-loop

Sorry but I did not realise this was still open. Thanks for your comments but nothing altered the outcome so I used a different product which caused no problems.
