Configuring NAT and Firewall Traversal

About this task
®
Avaya Scopia XT Series fully supports NAT and firewall traversal, enabling you to place it behind a
NAT router or firewall and connect with other endpoints seamlessly.
If an XT Series located inside your network hosts a call on its built-in MCU, other endpoints must
contact the host unit by dialing its IP address. However, when sitting behind a NAT or firewall, a
device can have an internal IP address which cannot be reached from outside the network. This
poses a problem for endpoints located outside the network to find the correct IP address to dial.
There are several ways to resolve this:
• (Recommended) Contact a STUN public server to return your IP address as it looks from
outside the network, and then send this public IP address to all endpoints you invite to the
meeting. This is known as STUN auto-discovery. This also works for HTTP public servers.
• Use a dedicated firewall traversal solution like the Avaya Scopia
as your gatekeeper (see
• You can manually set a static public IP address of the unit, and configure your firewall and NAT
to ensure this is reflected externally outside the network.
For more information on each of these topologies, see
