Polycom 6000 manual H.460 NAT Firewall Traversal

Networks

2Configure these settings in the Firewall screen:

Setting	Description
Fixed Ports	Lets you specify whether to define the TCP and UDP ports
	 If the firewall is not H.323 compatible, enable this setting.
	The Polycom QDX 6000 system assigns a range of ports
	starting with the TCP and UDP ports you specify. The
	system defaults to a range beginning with port 3230 for
	both TCP and UDP.
	Note: You must open the corresponding ports in the
	firewall. You must also open the firewall’s TCP port
	1720 to allow H.323 traffic.
	 If the firewall is H.323 compatible or the system is not
	behind a firewall, disable this setting.
TCP/UDP Ports	Lets you specify the beginning value for the range of TCP
	and UDP ports used by the system. The system
	automatically sets the range of ports based on the beginning
	value you set.
	Note: You must also open the firewall’s TCP port 1720 to
	allow H.323 traffic.
Enable H.460	Allows the system to use H.460-based firewall traversal. For
Firewall Traversal	more information, refer to H.460 NAT Firewall Traversal.
NAT Configuration	Lets you specify whether the system should determine the
	NAT Public WAN Address automatically.
	 If the system is not behind a NAT or is connected to the IP
	network through a Virtual Private Network (VPN), select
	Off.
	 If the system is configured behind a NAT that allows HTTP
	traffic, select Auto.
	 If the system is behind a NAT that does not allow HTTP
	traffic, select Manual.
NAT Public (WAN)	Displays the address that callers from outside the LAN use
Address	to call your system. If you chose to configure the NAT
	manually, enter the NAT Public Address here.
NAT is H.323	Specifies that the system is behind a NAT that is capable of
Compatible	translating H.323 traffic.
Address Displayed	Lets you choose whether to display this system’s public or
in Global Directory	private address in the global directory.

H.460 NAT Firewall Traversal

You can configure QDX 6000 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.

To use this traversal, Polycom QDX 6000 systems and firewalls must be configured as follows:
