Methods and Systems for Enabling NAT Traversal

Abstract

The invention relates to a method and system for facilitating traversal of NATs. The method includes a server providing NAT-related information for NATs of a first NAT type to at least one terminal in a first local network, the first local network comprising a NAT of the first NAT type. The NAT-related information for the NATs of the first NAT type enables the terminal in the first local network to traverse the NAT in that local network. NAT-related information obtained by testing a NAT of a specific NAT type, such as e.g. a specific brand, model, and/or firmware version of a NAT, may be re-used for other NATs of the same type, irrespective of the local network in which those NATs are used, thus alleviating the need to separately test the NATs of the same type in each local network that contains these NATs.
