Video Streaming over VPN
Posted on 2012-03-30
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
