Port forwarding is a technique that allows you to access a device or service on a network from a remote location. It is often used to access servers, webcams, security cameras, and other devices that are connected to a local network. Port forwarding can be useful in situations where you need to remotely access a device or service, but it can also be used for nefarious purposes, such as bypassing network security measures.
One way to set up port forwarding is to use Secure Shell (SSH), a network protocol that allows you to securely access a remote device or service over an unsecured network. SSH uses encryption to secure the connection, making it a safe and effective way to set up port forwarding.
The Serveo Method
The Serveo method is a technique for setting up port forwarding using the Secure Shell (SSH) network protocol. Serveo is a free, open-source service that allows users to set up port forwarding quickly and easily, without the need for a dedicated server or complex configuration.
To use the Serveo method, you will need to install an SSH client on your local machine. There are many SSH clients available, such as PuTTY for Windows and Terminal for macOS. Once you have an SSH client installed, you can use the following steps to set up port forwarding using Serveo:
- Connect to Serveo: To connect to Serveo, you will need to enter the following command in your SSH client:
ssh -R 80:localhost:80 serveo.net
This command forwards port 80 on the remote Serveo server to port 80 on your local machine.
- Test the port forwarding: To test the port forwarding, you can use a web browser to access the service on your local machine by entering “http://serveo.net” in the address bar. If the port forwarding is working, you should be able to access the service on your local machine.
It is important to keep in mind that Serveo is a free service, and it may not always be available or reliable. In addition, the port forwarding is only active as long as the SSH connection is open, so you will need to keep the connection active if you want to maintain access to the service.
In conclusion, the Serveo method is a simple and convenient way to set up port forwarding using SSH. It allows you to access devices and services on your local network from a remote location without the need for a dedicated server or complex configuration. However, it is important to be aware of the limitations of the Serveo service and take appropriate precautions to protect your devices and services.

Using Localhost.run Method
The Localhost.run method is a technique for setting up port forwarding using the Secure Shell (SSH) network protocol. Localhost.run is a free, open-source service that allows users to set up port forwarding quickly and easily, without the need for a dedicated server or complex configuration.
To use the Localhost.run method, you will need to install an SSH client on your local machine. There are many SSH clients available, such as PuTTY for Windows and Terminal for macOS. Once you have an SSH client installed, you can use the following steps to set up port forwarding using Localhost.run:
- Connect to Localhost.run: To connect to Localhost.run, you will need to enter the following command in your SSH client:
ssh -R 80:localhost:80 ssh.localhost.run
This command forwards port 80 on the remote Localhost.run server to port 80 on your local machine.
- Test the port forwarding: To test the port forwarding, you can use a web browser to access the service on your local machine by entering “http://ssh.localhost.run” in the address bar. If the port forwarding is working, you should be able to access the service on your local machine.
It is important to keep in mind that Localhost.run is a free service, and it may not always be available or reliable. In addition, the port forwarding is only active as long as the SSH connection is open, so you will need to keep the connection active if you want to maintain access to the service.
In conclusion, the Localhost.run method is a simple and convenient way to set up port forwarding using SSH. It allows you to access devices and services on your local network from a remote location without the need for a dedicated server or complex configuration. However, it is important to be aware of the limitations of the Localhost.run service and take appropriate precautions to protect your devices and services.

Using a dedicated server
To set up port forwarding using a dedicated server or virtual private server (VPS), you will need to install an SSH server on the server and connect to it from your local machine. Here is a step-by-step guide on how to set up port forwarding using a dedicated server:
- Install an SSH server: To set up port forwarding, you will need to install an SSH server on your dedicated server or VPS. There are many SSH servers available, such as OpenSSH or Dropbear. Follow the instructions for your chosen SSH server to install and configure it on your server.
- Connect to the server: Once the SSH server is installed and running on your server, you can connect to it from your local machine using an SSH client, such as PuTTY for Windows or Terminal for macOS. To connect to the server, you will need to enter the server’s IP address and the default SSH port (22) in the SSH client. You will also need to enter the username and password for the server to log in.
- Forward the port: Once you are logged in to the server, you can use the “ssh -L” command to forward a port. For example, to forward port 8080 on your local machine to port 80 on the server, you would use the following command:
ssh -L 8080:localhost:80 user@server_IP
- Test the port forwarding: To test the port forwarding, you can use a web browser to access the service on the server by entering “http://localhost:8080” in the address bar. If the port forwarding is working, you should be able to access the service on the server.
It is important to keep in mind that port forwarding can be a security risk, as it allows external access to your server or device. Make sure to use strong passwords and keep your server and devices up to date to reduce the risk of unauthorized access.
In conclusion, setting up port forwarding using a dedicated server or VPS is a simple and effective way to access devices and services on a remote network. With the right tools and knowledge, you can easily set up port forwarding and remotely access your devices and services from anywhere. However, it is important to be aware of the security risks associated with port forwarding and take appropriate precautions to protect your devices and services.
The Bottom Line
It is important to keep in mind that these methods are only suitable for simple port forwarding scenarios. For more complex port forwarding configurations, you may need to use more advanced techniques or tools.
There are several easy methods for setting up port forwarding using SSH, such as using the Serveo or Localhost.run services, or using a dedicated server. These methods are simple and convenient, but they may not be suitable for all port forwarding scenarios. It is important to choose the right method based on your needs and resources.
