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, please verify the service port number before the configuration.
Important:
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 the IP Address is a public one or private one, please refer to this link:
http://en.wikipedia.org/wiki/Private_network
How to check the WAN IP of Cudy?
Wireless Router & Mesh (System Status->WAN->Status)

4/5 Router (System Status->Cellular/4G->Status)

Note:
1. Usually, if the Public IP and IP Address are the same, it means you've got a Public IP. 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 internet. So if the Cudy router gets private IP address, you need to figure out which device use this Public IP and open ports on it.
2. For most of the cellular router, 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 in their part.
Step 1: Open a web browser and go to http://cudy.net or http://192.168.10.1.
For details, please refer to How to log into the web interface of Cudy Router?
Step 2: Click Advanced Settings -> Port Forwards in the Network section.

Step 3: Click Add to append one entry to the list. Input the parameters as you want into the field as below.

For example: According to the following configure, TCP port 5000, UDP port 5001 and both TCP/UDP port 6000 of host 192.168.10.18 will be opened to the internet.

Name:
Name of the entry, used to facilitate memory
Protocol:
TCP, UDP or TCP+UDP
External Port:
Service port on the WAN side which can be accessed to from the internet
Internal IP address:
IP address of the host, which will open the port to the internet
Internal Port:
Service port of the host in the LAN
Note:
Generally, internal port is the same as the external port.
Step 4: Click 'Save & Apply' to save the settings.
Go to the Status page and check the WAN IP Address of the router. Now you can try to use the http:// WAN IP: port number to visit the service you have opened.

@Dear Yuri,
Our technical support has contacted you via email. Please check.
“I eagerly awaited a response from someone who could help me with the problem I described… I followed your instructions and set up the ZeroTier network. But it doesn’t solve my problem!
The host I want to connect to via RDP does not have the ZeroTier network client – Windows 8.1. I installed different versions from 1.6.6 to 1.8.8, but the network on the host did not start (the firewall is disabled).
Perhaps to connect from my host (with ZeroTier), I only need one rule in the routing on the cudy 3600 router located in ZeroTier, and/or to create a bridge?”

@Dear Yuri,
You can add Routing rules on the Zerotier Management console page to meet you requirement. Please refer to this article on the website.

“There is a Zerotier network with one host and one router. Physically, they are located in different networks with different providers behind grey IPs. How can I redirect an RDP connection on the router to another host that does not have Zerotier and is located in the same local network as the router?”

@Dear Giulio,
If the device you want to access is a windows computer. Please try to disable the firewall of the cpmputer and try again.
In addition, the device you want to access must set the correct gateway IP address (which is the LAN IP address of R700).
“I’m setting up a Wireguard vpn server on R700. The connection is successful and I can access the R700 web interface but no other IP. It seems that the vpn is not routed correctly. But in the router interface there are no advanced commands to manage the nat and I can’t access via ssh. How can it be solved”
