How to configure the OnCell device as a virtual server
In the OnCell device’s web console, you will find a virtual server settings page where you can set up multiple
Ethernet devices connected to the OnCell device:
As you can see, virtual server setting is basically setting the forwarding ports. For example, you select an
available public port that the OnCell’s WAN IP will be listening on. A TCP client device will connect directly
to the OnCell’s WAN IP/Public Port when making a TCP connection with the server. Next, enter the actual
server’s IP address (Internal IP) to allow the OnCell to locate the server in the local network. An internal port
(listening port on the actual server) is then specified so that the traffic coming through from the public port
will be forwarded to the internal port. Lastly, you’ll notice that both TCP and UDP traffic can be forwarded by
the virtual server.
The previously mentioned DDNS function can be enabled on the OnCell device to compensate for dynamic
WAN IP addresses:
