Having a dedicated NAT/firewall traversal server like the SCOPIA PathFinder offers
external endpoints a static address when joining conferences hosted in your organization.
You can dial [email protected] to access from outside the firewall, or you
can dial 1234 directly if you are a H.460 client logged in to the SCOPIA PathFinder Server.
H.460 is an extension of the H.323 protocol used for NAT and firewall traversal, employing
ITU-T standards. The traversal server can be a a SCOPIA PathFinder or a third-party ITU-T
compliant server.

Using a NAT and Firewall Traversal Server
Configure the traversal server as the XT Codec Unit gatekeeper and enable the H.460
option. Configure the XT Codec Unit to the IP address of the traversal server SCOPIA
PathFinder.

Using the XT Series for NAT and firewall traversal
In cases where your organization has no sophisticated firewall protection, the XT Series
can straddle the two network zones using the two network ports provided on the XT Codec
Unit (see
Figure 1-4 on page 7
).
Use the GLAN ports of the XT Codec Unit simultaneously and connect one port to the
public network and the other to your private network. All communication passes through
the XT Series which acts as the virtual conference room for all the endpoints.
