Before You Start:

Port forwarding should only be used when the devices need to be accessed via the internet. To ensure proper security configuration, please follow below points:

1. Minimize the port numbers exposed to the internet. Port forwarding should only be configured when absolutely necessary. For example, to use web service, only port 443 should be forwarded.
   

2. Avoid common ports and reconfigure them to customized ports. For example, port 80 is commonly used for HTTP. User is recommended to change to a customized port on the device other than port 80 for the designated service, following TCIP/IP port rule (1 – 65535).
   

Steps:

1. Go to Configuration -> Advanced Configuration -> Network -> General to correctly configure network parameters to make sure your device is accessible in LAN. DNS server address is necessary in this case.
   

2. Click Apply to continue.
   

3. Go to Menu->Configuration->Network->NAT to check ‘Enable UPnP’;
   

4. Login router management interface via web and enable UPnP function.
   

Note:

1. The Mapping Type is recommended as Auto.
   

2. The (External) Port as well as External IP Address will be refreshed if all the configurations are correct. And UPnP Status will be Active.
   

Method 2: Configure Port Forwarding Manually Steps:

1. Go to Configuration -> Advanced Configuration -> Network -> General to correctly configure network parameters to make sure your device is accessible in LAN. DNS server address is necessary in this case.
   

2. Click Apply to continue.
   

3. Go to Menu->Configuration->Network->More Settings to check the ports you need to open.
   

4. Login router management interface via web;
   

5. Go to Forwarding to open ports for device.
   

Note:

The port forwarding interface above is for ASUS router (AC68U), which maybe distinct from other router’s interface.
