Planning NAT and Firewall Traversal with Avaya Scopia ® XT Series
Figure 1: Using an HTTP/STUN Server for NAT and Firewall Traversal
This approach works well in simple NAT and firewall traversal deployments, typically used by
home offices and Small Medium Businesses (SMBs).
• 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 both network ports provided on the XT Codec Unit
(see Figure 2: Using XT Series for NAT and Firewall Traversal on page 22).
Activate the second network port with the correct license, then 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.
