Abstract

Official abstract text for this publication.

A DNS server ( 110 ) and to a method of managing a DNS request, the method comprising receiving (E 2 ) a DNS request for accessing a remote application ( 104 B) accessible via a gateway ( 106 B) and sending (E 3 ) a DNS response including the IP address of the gateway ( 106 B), the method further comprising a verification for determining whether a port range identifier is stored in the DNS server ( 110 ) in association with the IP address of the gateway ( 106 B), and if so, the identifier is inserted in the DNS response before sending the DNS response. The invention also provides a method of transmitting data from a first gateway ( 106 A) to a second gateway ( 106 B), a method of transmitting data from a gateway ( 106 B) to a server ( 102 B) of a local network (LAN_B), and the gateways ( 106 A, 106 B) for performing such methods.

First claim

Opening claim text (preview).

The invention claimed is: 1. A method of managing a DNS request carried out by a DNS server, said method comprising: receiving a DNS request from a first gateway in order to access a remote application accessible via a second gateway, the first gateway and the second gateway each being allocated a shared IP address which is shared with at least one client device to which the shared IP address is allocated and a range of a plurality of ports for the shared IP address; sending to…
