In the application settings window, select Security Controls → Device Control.
In the Access settings block, click the Anti-Bridging button.
In the Rules for devices block, select the rule whose priority you want to change.
Use the Up / Down buttons to set the priority of the connection rule.
The higher a rule is positioned in the table of rules, the higher its priority. Anti-Bridging blocks all connections except one connection established using the type of device for which the highest-priority rule is used.
