Firewall Traversal

TANDBERG VIDEO COMMUNICATION SERVER ADMINISTRATOR GUIDE

Configuring the VCS as a Traversal Server

Configuring Traversal for Endpoints

Traversal-enabled H.323 endpoints can register directly with the VCS Border Controller and use it for firewall traversal.

To configure the options for these endpoints:

•VCS Configuration > Border Controller > Locally Registered Endpoints

You will be taken to the Locally Registered Endpoints page.

•xConfiguration Zones LocalZone Traversal H323

H.323 Assent mode

Determines whether or not H.323 calls using Assent mode for firewall traversal will be allowed.

H.460.18 mode

Determines whether or not H.323 calls using H.460.18/19 mode for firewall traversal will be allowed.

H.460.19 demux mode

Determines whether the VCS will operate in Demultiplexing mode for calls from locally registered endpoints.

On: allows use of the same two ports for all calls.

Off: Each call will use a separate pair of ports for media.

H.323 preference

If an endpoint supports both Assent and H.460.18 protocols, this setting determines which the VCS uses.

UDP probe retry interval

Sets the frequency (in seconds) with which locally registered endpoints will send a UDP probe to the VCS Border Controller.

UDP probe retry count

Sets the number of times locally registered endpoints will attempt to send a UDP probe.

UDP probe keep alive interval

Sets the interval (in seconds) with which locally registered endpoints will send a UDP probe to the VCS once a call is established, in order to keep the firewall’s NAT bindings open.

TCP probe retry interval

Sets the frequency (in seconds) with which locally registered endpoints will send a TCP probe to the VCS.

TCP probe retry count

Sets the number of times locally registered endpoints will attempt to send a TCP probe to the VCS.

TCP probe keep alive interval

Sets the interval (in seconds) with which locally registered endpoints will send a TCP probe to the VCS once a call is established, in order to keep the firewall’s NAT bindings open.
