Connection rules

On the Application settings screen, you can set up the rules for connections of this application to certain IP addresses and ports.

Creating a rule

1.To create a new rule, tap Add rule in the Rules for IP addresses and ports section. You can add allowing or blocking rules depending on the selected option:

•Block connections from the list – to add a blocking rule.

•Allow only the connections from the list – to add an allowing rule.

2.In the opened window, enter a valid IP address in the Server address field (in the a.b.c.d format), an IP addresses range (in the a1.b1.c1.d1-a2.b2.c2.d2 format) or a network (in the a.b.c.0/n format, where n is a number from 1 to 32) or leave this field blank (in this case entering the port is obligatory).

Enter the valid port in the Port field or leave it blank (in this case entering the IP address is obligatory). If you leave one of the fields blank, the rule will be valid for all the IP addresses or ports respectively. Tap OK to save the rule.

If you have selected the Allow only the connections from the list option, but have added no addresses to the list, the application will block all connections.

3.To edit an existing rule, tap and hold it, then tap Edit.

You can also add allowing and blocking rules viewing the applications logs or the list of current Internet connections.

Deleting connection rules

•To delete a rule, tap and hold it, then tap Delete.

•To clear all rules for a certain application:

1.Select this application from the list (see Figure 22).

2.In the application menu, select Clear.

3.In the opened window, select the Clear rules for this app check box. Tap OK.

•To clear all rules for all applications:

1.On the applications screen (see Figure 22), open the application menu and select Clear.

2.In the opened window, select the Clear rules for apps check box. Tap OK.

Incoming connections

To allow incoming connections for an application:

1.On the Applications (see Figure 22), select the application to allow incoming connections for.

2.On the Application settings screen, open menu in the top right-hand corner.

3.Select the Allow incoming connections check box.

The information on the connections from any external addresses with the port opened by the application is only partially added to the application log and firewall statistics. Moreover, any connections with such addresses may be excluded from firewall check for all other applications. This operation mode is not safe and should not be used.

Allowing the incoming connections is useful in case the firewall cannot be disabled by other means, for example, when a server receiving connections from external networks is configured on the device.
