SYSTEM FOR THE ROUTING OF DATA TO COMPUTER NETWORKS

The system (S) for the routing of data to computer networks comprises: a server unit (SRV) connected to a public network (I); a local area network (Prop. LAN 1, . . . , Prop. LAN m) having at least a client device (CL1, . . . , CLn); a routing unit (FW1, . . . , FWm) having a first network interface (eth0) connected to the public network (I) directly or indirectly through a local area network of third parties (3p LAN 1, . . . , 3p LAN m) and having a second network interface (eth1) connected to the local area network (Prop. LAN 1, . . . , Prop. LAN m); wherein to the first network interface (eth0) is assigned a public IP address or a private IP address determined by the local area network of third parties (3p LAN 1, . . . , 3p LAN m); and wherein to the local area network (Prop. LAN 1, . . . , Prop. LAN m) is assigned a predefined class of private IP addresses; wherein routing unit (FW1, . . . , FWm) comprises automatic routing means (VM0) of data between the server unit (SRV) and the local area network (Prop. LAN 1, . . . , Prop. LAN m) independently of the IP address assigned to the first network interface (eth0).
