How to Port Forward TELNET

TELNET is a very old and very basic protocol for communication between computers.  Because it is so old, it is not often used today except in very specific circumstances. One of those circumstances is when you need to port forward TELNET.

Port forwarding TELNET is actually quite simple. You just need to tell your router that any traffic coming in on port 23 (the TELNET port) should be forwarded to the IP address of the computer that you want to use TELNET on.

To port forward TELNET, you have to follow our step-by-step guide below.   

Requirements to Port Forward TELNET

Just before you begin with the process of port forwarding, make sure you have the following things:

• The IP address of your router.
• IP address of your gaming device.
• TCP and UDP ports of TELNET for your gaming device as mentioned in the section below.

Step-by-step guide on how to port forward TELNET

Now that you have the above details noted down, you can move to the next stage of TELNET port forwarding:

1. On your web browser address bar, type your router’s IP Address/Default Gateway.
2. Log in with your router’s credentials (username and password) to view your router’s firmware settings.
3. Navigate to the port forwarding section of your router.
4. Click on Port Forwarding.
5. Enter the IP address of your gaming device in your router in the correct box.
6. Put the TCP and UDP ports of the TELNET server in the boxes in your router. The default TELNET port number is 1025. And then click the apply button.
7. And you’re done. Restart your router to let the changes take effect.
8. Once your changes take effect, now you can connect to TELNET.

How to open ports behind CGNAT

What if your ISP performs CGNAT? Most ISPs perform CGNAT (Carrier-grade Network Address Translation) to conserve bandwidth and assign a single IP address to multiple users connected to the same internet network. However, CGNAT makes it difficult for you to open ports on the router. 

To get around the CGNAT issue, you can use the Port Forwarding add-on to bypass this problem and port forward routers without hassle. 

Here’s more information on how to use PureVPN’s Port Forwarding add-on and bypass CGNAT in a few clicks.

A secure way to open all ports

To most people, port forwarding is quite a demanding task. For starters, every router has a different console, which often makes it difficult to navigate to specific settings.

Secondly, you won’t always be able to open TELNET ports on your router if your ISP restricts the ports. Yes, you heard that right! ISPs are notorious for blocking ports due to security reasons. If ISP isn’t the reason behind a blocked port, then perhaps it could be your operating system’s firewall.

Well, you can make all these problems go away and enjoy smooth online gaming on all your desired systems with PureVPN’s Port Forwarding add-on. Through the Port Forwarding add-on, you can allow all ports, disallow all ports, and allow specific ports.
