Having BM35 server with double NAT. Need to open ports for the video conference. Assign one private IP for the VideoPhone and had add a
secondary IP to the NAT table. Add two filters as follows:

Source Int: Public Dest Int: All
Packet Type: tcp
sOURCE pORT: ALL Dest Port: 1024-2100
Source Add Type: Any Address
Dest Add Type: Host (210.24.39.216)- address assigned to the
VideoPhone

The same configurations goes to the UDP protocols.
However, I am able to register successfully with the other end but
when I
tried to call to the VideoPhone, it gives me an error. What could be happening? Pls help...
