Network application association

A method for controlling packet communications between a first network and a second network, the method comprising:

• associating, with the assistance of the server and driver modules, a network address and port used by the first node with a predetermined application, wherein the network address and port is used for sending at least one packet of the application to a second node in the second network;
• and
• executing packet communications between the server module and the driver module to inform the connecting node about the network address and port used by the first node for the predetermined application before the first node sends a first packet of the application to the second node, wherein the network address and port used by the first node and information for identifying the predetermined application are included in a predetermined data portion of at least one packet exchanged between the server module and the driver module.
