Firewalls

You can configure and manage your firewall from within the FlashPanel console via the Network tab on the server's management console. Firewalls are used to open ports on your server to the Internet. For example, when using FTP, you may need to open port 21. For added security, you can restrict opened ports to specific IP addresses. Steps to configure a firewall:

1. At the Network tab > click the Add Firewall Rule button:

2. Fill out according to instructions

   • Port: You can specify a port such as 3306, 5432 or you can also open a range of ports: for example, if you want to open a range of ports from 8000 to 8010, enter: (8000:8010)
   • Allow/Deny rule type: You can choose to allow or deny traffic for a certain rule. By creating a deny rule, you will prevent traffic from accessing the service.
