The technique of rerouting network traffic from one port on a server to another port on the same server or to a different server within the same network is known as port forwarding in Plesk. As part of our Plesk Hosting Support, Bobcares provides answers to all of your questions.

Port Forwarding in Plesk

When applications or services are running on non-standard ports or for security reasons, port forwarding is used to reroute traffic from one port on the server to another. Let’s see how port forwarding works in Plesk in the following section:

1. Plesk enables users to run a variety of programs as well as services on their servers, including mail servers, database servers, and web servers. Usually, each of these services keeps an eye on certain network ports for incoming connections.

2. Firewalls are used in many server setups in order to control both inbound as well as outbound network traffic. For security purposes, firewalls often prevent inbound connections to the majority of ports by default. However, for some services hosted on non-standard ports, users may have to grant external access.

3. The port forwarding rule setup interface offered by Plesk is easy to use. Users can also use the Plesk control panel to access this interface. They can designate the target IP address and port to which the traffic is to be routed, in addition to the source and destination ports.

Use-cases

1. Managing Several Websites:

When a server serves many websites, each operating on a separate port (for example, 80 or 443 for HTTP and HTTPS), port forwarding can be set up to reroute incoming traffic to the relevant web server instances on those specific ports.

2. Reaching Out to Remote Services:

It’s possible that users will wish to use remote access to services housed on their server. A service operating on an internal IP address and port can receive traffic from a specific port on the server’s public IP address using port forwarding.
