1. Enter the external network access port in External Port, such as "8080". "External ip Address" defaults to the current wan address;

2. Enter the ip of the internal server in "Internal ip Address", such as "192.168.2.8";

3. Enter the port of the internal server in "Internal Port", such as "80" of the web service, depending on what service you are, the port number of different services is different.

4. ok. Rules can be added to the list below. All right!

Now, you can use "IP of wan: 8080" on the external network to access the web service of the internal network.

For example, I mapped the "192.168.2.10" remote desktop port "3389" of the internal network to the "62222" port of the external network "xx.xxx.xxx", which can be connected anywhere in the world by "remote desktop connection".

If you want to access the setting interface of this route in the external network, you can map the "80" port of Huasan Route's local area network (for example,192.168.2.1) to a port of the external network (use a larger port instead of 80), and then you can directly access the routing settings by the above method.
