Method for operating a local computer network connected to a remote private network by an IPsec tunnel, software module and IPsec gateway
First Claim
1. Method for operating a local network (RES_L) comprising a local terminal connected to a gateway of a remote network by a blocking tunnel, which method includes an operation of routing flows from the terminal (T_L) to the gateway (PASS_D) through the blocking tunnel, characterized in that it also includes:
- an operation of sending a flow not intended for said network implemented in the gateway (PASS_D) and consisting of sending said flow from the terminal (T_L) intended for an apparatus of the local network to said local equipment (E_L, ad—

Abstract
The invention relates to a method in particular enabling the computer terminal (T_L) of a local network (RES_L), connected to a gateway (PASS_D) of a remote network (RES_D) by an IPsec tunnel in blocking mode, to launch a print job on a printer (E_L) belonging to the local network. To do this, the gateway (PASS_D) stores the correspondence between the public address (AD_1) of the local router (ROUT_L) providing the connection of the terminal to the Internet, and the private address (ad_3) assigned to the terminal (T_L) in the addressing plan of the remote network (RES_D) during the establishment of the tunnel, and sends the print flow to the local router (ROUT_L), which directs it to the local printer (E_L) by a port translation technique.
