Polycom VSX/HDX Private IP vs Nat'd IP

Hey Guys,

I’ve got a bit of a weird problem with a few of our Polycom VSX and HDX systems and talking to one another. The Polycom systems that are on the same IP Subnet or routed to a separate IP Subnet via Private WANs are unable to communicate with each other.

I’ve done a packet capture and what the call signalling is happening perfectly fine when using TCP, but as soon as UDP packsets start to flow the Polycom systems are using the External Nat’d address, which of course is screwed by the routing tables.

How do make it so the Polycom systems are only adding the private IP addresses to their packets and have our Firewall/Router handle all the NATing ?

Thanks
Andrew

Just to clarify one statement - you state Polycom systems that are on the same IP Subnet are unable to communicate.  I can see that this could be an issue across WAN's and different subnets but your statement leads me to believe that it is across WAN to LAN and from LAN to LAN.  Can you clarify?

ALso, can you provide a little drawing of what is where and what switch/router/firewall gear is between what.
