A subnet is a neutral zone and is connected through the telecom egress.Internet, Gateway is set192.168.1.254A subnet uses a vro leased line to connect to a large internal network. The Gateway is set10.1.8.254. Each machine has two NICs and two gateways.[Generally, an important unit is to physically connect two networks at the same time, which is not safe.].

The simplest method is to combine various Gateway Routing knowledge on the Internet: 1.Set the connectionInternetThe gateway of the NIC is192.168.1.254The default gateway is enabled; 2.Connect the NIC of the IntranetIPAfter the configuration, set the gateway to null (that is, no gateway is set).
