You do not need to create or modify any rules for Panda GateDefenderPerforma to start working.
The only situation that may require a rule in the firewall to be modified is the GateDefender unit updates.
The firewall must allow Panda GateDefender Performa to connect to the Internet through ports 443 (https) and 80 (http) as these are used for the updates of the different modules. Similarly, port 53 should also be open for name resolution.
As version 2.03.00.0000 of Panda GateDefender incorporates the NTP service (a protocol used in IT system for synchronizing the time), if an external server is used as an NTP server, Panda GateDefender must be allowed to establish external connections through the firewall through UDP port 123.
