5.5 Allworx Server behind a 3rd-Party NAT Firewall
To support remote devices, Allworx Reach Mobile Clients, and SIP Proxy usage when the Allworx
server is behind a single 3rd-party NAT firewall, the server’s Network Mode must be in LAN Host
Mode.
When set to LAN Host Mode, the page contains a Public IP Address section as shown below:
As instructed on the page, enter the firewall’s public IP address in the Public IP Address field. In
addition, it may be necessary to configure the firewall to statically map specific ports. This is
described in the NOTE box on the web page and is discussed further in the document.
