Why Can't the Router Communicate with the Target Device after Port Forwarding?

Bachground:

The router establishes a VPN connection and cannot communicate with the target device after port forwarding.

 

1. Whether the network is open or not

Can other VPN clients ping the router's VPN interface IP?

Check the router's firewall - the reject in the Basic Settings is changed to accept.

Whether the firewall of the target subnet device is closed or changed to accept?

Whether the remote host device belongs to the same VPN server network?

 

2. hardware connection

Whether the target subnet device is connected to the WiFi of G806 or whether the LAN is connected correctly.

Whether the target subnet device is working properly?

 

3. Whether the parameter setting is correct

The remote VPN client or the host software on the server fills in the VPN interface IP and external port of the router where the target device located.

Whether the target subnet device opens the listening port and whether the listening port is the same as the internal port filled in the router

Whether the target subnet IP is the same network segment as the router LAN, and whether the gateway is the same as the router LAN port IP

The router sets whether the internal IP for port forwarding and the internal port are consistent with the information of the subnet device.

 

4. Other problems

Coordinate the man who is an FAE for the solution.
