Abstract
A method of allowing a data connection between a first node attached to a private IP network and a second node external to the private IP network and connected to a public IP network. The method comprises allocating a private network IP address, a hostname, and a service name to said first node, the service name associated with a service provided by the first node. A gateway allocates a unique public network side port number to the first node. A mapping between the private network IP address and public network side port is included in a connection table. Records are installed in a Domain Name System of the public IP network that include: a service record defining said hostname and public network side port number as the location for said service name; and an address record defining a public IP address of said gateway as the location for said hostname.
