How to configure the Port Forwards?
Port Forwards (Port forwarding) feature allows remote computers on the Internet to connect to a specific computer or service within the private LAN.
Different services use different service ports, verify the service port number before the configuration.
Make sure the Cudy router gets a Public IP (WAN IP) from your Internet Service Provider, if it’s a Private IP address that means there is another NAT device in front of Cudy. You need to open the service ports on that device as well.
For how to verify whether the IP Address is a public one or a private one, refer to
How to check the WAN IP of Cudy?
Wireless Router & Mesh (System Status->WAN->Status)
4/5 Router (System Status->Cellular/4G->Status)
1. The IP Address is the WAN IP Address you get from your Internet Service Provider. The Public IP above is the IP Address the other device can find you over the internet. So if the Cudy router gets a private IP address, you need to figure out which device uses this Public IP and open ports on it.
2. For most cellular routers, the internet service provider usually gives the private IP Address. So, if you want to do the port forwards, please contact your internet service provider to assign you a public IP address or do the port forwarding on their part.
