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.

@David,
Estimado cliente:
Gracias por contactar con el equipo de apoyo de cudy.
La dirección IPv4 de la interfaz de red de área extendida del enrutador no es una dirección IP pública. Por lo tanto, incluso si se establece ddns, no puede acceder a la interfaz Wan del enrutador. El nombre de dominio ddns estará relacionado con la dirección IP pública de la línea.
Compruebe si la dirección IP Wan del enrutador principal es la misma que la dirección IP pública que verificó en el enrutador. Si es así, primero debe configurar el reenvío del puerto en el enrutador principal y luego el reenvío del puerto en el enrutador cudy.
“Ccuando configuro mi DDNS en el router Cudy para configurar no-ip.com me arroja el siguiente alerta en color rojo: the current external network IP is not a public IP, and the DDNS service may not work properly.
la informacion detallada del router es la siguiente:
public ip: 38.51.156.145* (no se que significa el asterisco al lado de la ip)
direccion ip: 192.168.55.2
mascara: 255.255.255.0
pasarela: 192.168.55.1
dns: 192.168.55.1
En otra ventana me arroja esta informacion:
Wan
direccion ip: 192.168.55.2
Lan
direccion ip: 192.168.10.1
cabe destacar que tengo conectado el DVR a un mesh y a este dvr le coloque ip: 192.168.10.200"

“Hoello, I need to change external adress during port redirecting. Address is given by my intrnet provider but it is different then detected by router. Unfortunatelly, there is no such possibility in html interface (or I can’t find it?) Router model: NT12
Thank you”

“Hello,
I have an issue with setting port forwarding on LT700e.
It is supposed to be able to forward ports on VPN interface as well, but it does not work, ports are not forwarded correctly (they do not seems to be opened at all)
The purpose is to allow connecting to local service from other client in same VPN network.
VPN network itself seems to work fine.
Could you please advice?”
