Administrator’s Guide for Polycom HDX Systems

Visit the Polycom Security section of the Knowledge Base at www.polycom.com for timely security information. Systems deployed outside a firewall are potentially vulnerable to unauthorized access. You can also register to receive periodic email updates and advisories.

H.460 NAT Firewall Traversal

You can configure Polycom HDX systems to use standards-based H.460.18 and H.460.19 firewall traversal, which allows video systems to more easily establish IP connections across firewalls.

The following illustration shows how a service provider might provide H.460 firewall traversal between two enterprise locations. In this example the V2IU™ traversal server gateway is on the edge of the service provider network and facilitates IP calls between Polycom HDX systems behind different firewalls.

Service Provider

V2IU Server Gateway that Supports H.460.18 and H.460.19

Enterprise Location A

IP Network

System with

Traversal Enabled

Gatekeeper

Enterprise Location B

System with

Traversal Enabled

To use this traversal, Polycom HDX systems and firewalls must be configured as follows:

•Enable firewall traversal on the Polycom HDX system.

•Register the Polycom HDX system to an external V2IU Traversal Server Gateway that supports the H.460.18 and H.460.19 standards.

•Make sure that firewalls being traversed allow Polycom HDX systems behind them to open outbound TCP and UDP connections.

—Firewalls with a stricter rule set should allow Polycom HDX systems to open at least the following outbound TCP and UDP ports: 1720 (TCP), 14085-15084 (TCP) and 1719(UDP), 16386-25386 (UDP).

—Firewalls should permit inbound traffic to TCP and UDP ports that have been opened earlier in the outbound direction.

•For best interoperability, make sure that H.323 protocol-aware features are disabled on firewalls being traversed.
