This module can be used to manage firewall rules that define the type of access to the server's ports. A rule specifies which services will be allowed through your Firewall, and which ones will be kept out. Access rules define the parameters against which a connection is compared, resulting in a decision on what action to take for each connection.

There are three types of access rules in ISPmanager: Accept, Deny and Drop. Depending on the rule you specified, the incoming packets will be either allowed through Firewall or not. If Firewall detects a network connection it will search the rule that can be applied to this connection.

  • Access type - select a default type of access:
  • Open - all incoming packets will be allowed (except closed ones).
  • Closed - all incoming packets will be denied (except open ones). Note! Selecting this type of access means that all incoming packets except open ones will be denied by default. This may make your server inaccessible. You are not recommended to set this type unless you are an experienced user.

Once you have made changes to the firewall settings, restart the server to apply them.
