Figure 3: 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 Server for NAT and firewall traversal
In cases where your organization has no sophisticated firewall protection, the XT Server can
straddle the two network zones using the two network ports provided on the XT Codec Unit (see
Figure 4: Using XT Server for NAT and Firewall Traversal on page 16).
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 Server
which acts as the virtual conference room for all the endpoints.
