unit behind a NAT router or firewall and connect with other endpoints seamlessly. This section
describes the available methods to incorporate NAT and firewall traversal with XT Series:
• Using a Avaya HTTP server or a STUN public server for NAT and firewall traversal
When the XT Series hosts a videoconference with endpoints outside the enterprise
Using an HTTP/STUN Server for NAT and Firewall Traversal
HTTP or STUN server to discover its public IP address, then sends it to any external endpoints
wishing to join the conference. The external endpoints then answer the call using the IP
address provided. Configure the XT Series for HTTP or STUN autodiscovery. A STUN server
enables you to directly dial an endpoint behind a NAT or firewall by giving that computer's
public internet address.
Figure 8: 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 (Equinox H.323 Edge server) Avaya Equinox H.323 Edge or other H.460 server for NAT/
firewall traversal
Endpoints in the private network can communicate with public endpoints via an H.460 NAT/
firewall traversal server, like the Avaya Equinox H.323 Edge. Endpoints in the public network
