How to create general system rules in the firewall

 

In addition to creating specific rules for the programs installed, the firewall lets you create rules applicable to all the PC communications. These rules will have priority over the rules that you have established for the programs installed.

 

The general system rules let you open or close certain communication ports, allow or deny communications with computers with a certain IP address, etc.

 

You can create a general system rule, or configure an existing one, by following these instructions:

  1. Click Firewall in the main window of the program.

  2. In the Rules section, click Settings to define the ports and protocols that your PC can use to communicate.

This window contains the list of rules you have created and lets you establish the priority with which the rules will be applied. You can order them using the Up and Down buttons. The rule in the first place in the list will have priority over the rule in second place, and so on.

If you want to recover the original settings, click Restore.

  1. Click Add to create a new rule, or Settings to edit an existing rule.

Adding or configuring general system rules (Learn more)

There are certain parameters you can define when adding or configuring a rule:

In both cases, you can select one of the listed ports or choose any other one. If you want to select a specific port, select the Customized option and indicate the relevant ports or ranges. To add more than one port, separate them with commas. Ranges should be separated by a hyphen (For example: 6700, 6800, 6900-7000).

Note: You can specify more than one IP address or MAC address, separating them with commas. You can also specify a range of addresses, separated with a hyphen. For example, 192.168.1.1-192.168.1.254, 172.1.1.1 in the case of IP addresses, or 00:AF:C8:05:E0:FF,08:06:AC:15:E2:FF in the case of MAC addresses.

  1. Once you have made the changes you want, click OK.
