Abstract
The present invention relates to a method and arrangement of facilitating the establishment of peer-to-peer IP connections between a public network and hosts in a private or home network. The method uses a port mapping table residing in a NAT that maps external public IP addresses and external port numbers to private IP addresses and internal port numbers. This table has so far been configured manually by a user of the private or home network. Apart from being cumbersome, it demands skills in router and network technology, skills an ordinary user of a home network often does not have. The present invention solves this problem by automatically configuring the table comprising the steps of scanning the hosts using a port scanner and detecting the internal ports in the hosts that are in an open state.
