Abstract
A method for facilitating traversal of NATs includes a network node communicatively connected to a terminal in a local network that includes a NAT of a particular NAT type providing to a server a request for NAT-related information for NATs of that NAT type in a manner that enables the server to identify the NAT type. The method further includes the network node receiving from the server the NAT-related information for the NATs of that particular NAT type and providing the received information to the terminal, thus enabling the terminal to traverse it's NAT. In this manner, NAT-related information obtained by testing a NAT of a specific NAT type may be re-used for other NATs of the same type, irrespective of the local network in which those NATs are used, and the network node may serve as a proxy for the server for providing NAT-related information to terminals.
