Open ports on a Linode
In order to open ports on a Linode, you will first need to log in to your account and access the Linode Manager. From the Linode Manager, click on “System” in the left-hand menu and then click on “Port Forwarding” in the main window.
From the “Port Forwarding” window, you will need to click on the “+” button to create a new port forward. In the new port forward screen, you will need to enter the following information:
Server: the IP address or hostname of the Linode server you want to forward ports to
Port: the port number you want to forward
Protocol: the protocol you want to forward (TCP or UDP)
Server Address: the IP address or hostname of the machine you want the port forwarded to
You can optionally add a comment if you want. Click on the “Create Port Forward” button to create your port forward.
Once you have created your port forward, you will need to forward the ports using your router. In most cases, you will need to forward the following ports:
TCP: 80, 443, 25, 5223, 3306, and 5900
UDP: 88, 443, and 3478
Once you have forward the ports, you can test your port forward by accessing the Linode server using the port you forwarded and the server address you provided.
