Question about some settings...

Ive been reading different items on here so to understand how everything should work for a while but there were just a few things that I wasnt so sure about.

Iam not using a LAN/Router just a direct connection

When the firewall is set to learn, and you allow different applications access to and from the network, are the individual settings found within the Application Control Rules such as the Destination IP and Destination Port settings best set to ANY or is the best option to manualy list the exact ports/address that the applications should be communicating on ?

Ok, thanks for that…
