Adding Firewall Rules in Plesk

Windows servers using Plesk can use firewall rules to manage help manage server traffic. You can also add firewall rules using Windows Firewall, but adding firewall rules in Plesk is a good first line of defense. If you have a Linux server using Plesk, it’s likely you are using CSF as your firewall solution, which is not controlled via Plesk.

Firewall Rules in Plesk

1. Log into your Plesk control panel.
2. In the left navigation menu, click on Tools & Settings.
3. In the Security Section, click on Firewall.
4. Click on the Firewall Rules tab. You’ll see a list of all the current Plesk firewallrules.
5. There are multiple default firewallrules. Some default rules are not editable, as they are integral to your server functioning properly. Either click on a rule to edit it or click on Add Firewall Rule. 
6.  Fill in the fields to set your rule’s properties. How you fill in the fields will vary based on what you want your rule to do. Some common examples:
   • • Deny connections on a specific port number.
   • • Deny connections from specific IPs on a specific port number.
   • • Allow connections on a specific port number.
   • • Allow specific IPs to connect to specific ports.

   (If you want to deny an IP from accessing your server at all, we recommend contacting the Windows Support team.)

7. Once you’ve created or edited your rule, click OK.
