Abstract: A method for managing network traffic between one or more user equipment devices in a private network and a server outside the private network via a private gateway, a server gateway and a connection therebetween. The server gateway acts as a router and the private gateway acts as a bridge. The method including monitoring the connection between the private gateway and the server gateway; in the event of loss of connection, switching the private gateway from a bridge operation mode to a minimal service mode; repeating the previous method steps; in case of retrieved connection, switching the private gateway from the minimal service mode back to the bridge operation mode; and repeating the previous method steps. The private gateway provides minimal routing services to allow data traffic in the private network to continue in the minimal service mode.
