4GRouter allows to reach from the Internet any device connected to it (for
example an IP camera).
To use this feature it is necessary to configure Port Forwarding rules.
Each device connected to 4GRouter is part of its local network, is identified by
a private IP address and can have a certain number of internal communication
ports. Through Port Forwarding it is possible to associate a specific external
port to each internal port. In this way, the incoming traffic from the Internet,
addressed to the public IP of the router (or the host name of the DDNS) on a
specific external port, is forwarded by the router to the device with the
associated internal port.
Example:
Public IP address of the router: 2.192.118.1
Host name: xxxxxx-xxxxxx.dyndns-ip.com
Private IP address of the camera connected to the router: 10.130.1.226
Internal port of the camera: 80
Port forwarding: associates internal port 80 to external port 88.
The camera can be reached from the Internet via the following URL:
xxxxxx-xxxxxx.dyndns-ip.com:88
