For example, if a PC on the LAN is hosting a website that must be accessible from the Internet, its http port
(port 80) must be exposed through the firewall. To permit access to this web server, create a new entry,
entering 80 for the WAN Port #. Choose TCP for the Protocol, enter the PC’s IP Address (e.g. 192.168.101.9)
and the Local Port # of 80.
Note: The WAN and LAN Port #s must always be the same.
If port 80 of a PC on the LAN is exposed this way, the Allworx port 80 http service must be
disabled. Uncheck the HTTP (80) checkbox in the Allworx Services section of the page. If the
Allworx Internet web page is to be used, leave the Allworx HTTP box checked and change the
http port on the PC to some other port number (e.g. port 5000).
Due to security requirements, the Allworx
server’s LAN IP address should not be used as an IP Address, in
the table above. Port 8080 of the Allworx server is never exposed to its WAN interface. To access the
Allworx LAN interface from the Internet, use the server’s VPN feature, instead.
