Abstract
The invention relates to a network node for facilitating traversal of NATs. The network node includes a NAT, a server configured for exchanging one or more messages with a client to enable the client to determine NAT-related information for the NAT, and a routing unit configured for routing the one or more messages exchanged between the client and the server via the NAT. Implementing the server on such a network node eliminates the need of having the server deployed in the WAN, thereby allowing faster determination of the NAT-related information, while the routing unit ensures that the messages traverse the NAT unit. In this manner, a NAT information provider (NIP) may request NAT behaviour discovery and obtain NAT-related information. After that, the NIP is able to provide appropriate NAT-related information to terminals in local networks, thereby enabling the terminals to traverse the NATs that they are behind.
