I have to set up videoconferencing to an external location over the internet.
The system, eyecatcher, is behind the firewall and i opened all the required ports on the wachtguard firebox.
Problem is that the the destination vcon receives my call and pickes it up. But my system doesn't get this information back from the calling system. The supplier of the system says that my system doesn't receive the ip-packets related to port 7020.(ps when connecting the system straight to the internet i have no problems)
however in my firebox/firewall i don't see a drop.
I tried to set an incoming rule to all_trusted and even forwarded the incoming ports related to videconfering straight to the ip adress of my eyecatcher. Nothing worked.
I have browsed the internet to see which models/makes of firewalls are compatible with videoconfering (h.323 protocol) but this seems to be a gray area
any help is appreciated.
