How do I open ports on modem router (self-developed UI)?

Step 1 

Open the web browser and type the IP address of the device in the address bar (default is 192.168.1.1). Press Enter.

 

Type the username and password in the login page, the default username and password both are admin, Then click OK to log into the device.

 

Step 3 

Click Forwarding->Virtual Servers on the left side to open the Virtual Servers Setup page. Then click Add New.

 

Step 4 

Type the Service port which you want to open and the IP Address of your computer or server; Select Protocol to TCP, UDP or ALL; Change Status to Enabled or You can choose the option Common Service port and select a service in the list, then the port for the computer or server will be put into the entry automatically.

 

Click Save to save the settings.

 

You´d better assign a static IP address for your computer or server, so the Virtual Server entry will take effect all the time.
