The TCP IP forwarding feature, restrict access to administrative services like SSH and RDP from the public internet and keeps your backends safe from potential attacks. This guide explains how to port forward Tcp/ip.
Requirements to Port Forward Tcp/ip
Just before you begin with the process of port forwarding, make sure you have the following things:
- Downloaded and installed the Tcp/ip server.
- The IP address of your router.
- The IP address of your device.
TCP and UDP ports of Tcp/ip for your gaming device as mentioned in the section below.
Step-by-step guide on how to port forward Tcp/ip
Now that you have the above details noted down, you can move to the next stage of Tcp/ip port forwarding:
- On your web browser address bar, type your router’s IP Address/Default Gateway.
- Log in with your router’s credentials (username and password) to view your router’s firmware settings.
- Navigate to the port forwarding section of your router.
- Click on Port Forwarding.
- Enter the IP address of your device in your router in the correct box.
- Put the TCP and UDP ports of the Tcp/ip server in the boxes in your router. The default Tcp/ip port number is 475. And then click the apply button.
- And you’re done. Restart your router to let the changes take effect.
- Once your changes take effect, now you can host a Tcp/ip server and let your friends connect to it as well. To let them connect to it, you need to provide them with the hostname you are using, along with the port number. For example, ‘hostname.domain.com:25565’.
Tcp/ip ports needed to run
To access Tcp/ip online and create a server without any interruptions, you’ll have to allow access to certain ports on your firewall. The default Tcp/ip ports are:
| TCP Port: | 443, 475 |

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.
PureVPN’s Port Forwarding Add-on
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 TCP/IP 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 eliminate all these problems 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.
Frequently Asked Questions
What is TCP IP forwarding?
With IAP’s TCP forwarding feature, you can restrict access to administrative services like SSH and RDP from the public internet. This keeps your backends safe from potential attacks.
How do you know if a port is TCP or UDP?
A TCP socket gets created with AF_INET (or AF_INET6) and SOCK_STREAM. A UDP socket uses SOCK_DGRAM instead of SOCK_STREAM.
Is there a safe way to port forward?
It may sound daunting, but you can easily set up a port forward in your router by following these safety measures: using a firewall, having a strong password on the device that you are forwarding ports to, and only forwarding ports for trustworthy applications.
