By default, on Plesk instances deployed from Amazon Lightsail images, Plesk interface and a number of Plesk services (for example, FTP, mail, and databases) cannot be accessed. This is because the ports required for them to operate are blocked by the Amazon Lightsail Firewall. To access Plesk and use these services, you need to manually allow connections to specific ports or port ranges.

By default, on Plesk instances on Amazon Lightsail all outgoing connections are allowed, and all incoming connections are blocked. Exceptions are made for connections to ports listed in the table below.

Access to Plesk interface and Plesk services using ports not listed in the table above is blocked. To allow access to Plesk interface and one or more blocked Plesk services, you need to open the corresponding ports in the Amazon Lightsail Firewall.

To allow access to a Plesk service on an Amazon Lightsail instance:

1. Go to Amazon Lightsail Home.

2. Under “INSTANCES”, click the name of the desired instance, and then go to the “Networking” tab.

3. Under “Firewall”, click +Add another and specify the following settings:

   • “Application”. Keep the default “Custom” value.

   • “Protocol”. Select the required protocol (TCP or UDP) from the drop-down list.

   • “Port range”. Specify the port or port range corresponding to the Plesk service you want to allow access to.

     

4. Click Save.

To access Plesk for the first time, you need to allow access to the services listed in the table below.

The following table shows the list of ports different Plesk services require to operate. For security reasons, we recommend that you allow access only to services you want to use. Keep the ports corresponding to the services you do not want to use closed. For example, if you want to use mail, open all ports listed in the “Mail” section.

For the list of ports you need to open to allow migrating customers and domains to or from your instance, read Migration Prerequisites.
