Routes and switches

I need to build my own network on the Intranet.

Configure the network and use the DHCP service. What should I do? When DHCP is used, the WAN port of the route is first connected to the Intranet, and then the first port of the switch is connected to the LAN port of the route. Then you can connect all the machines you want. In addition, no direct connections are used, all of which are twisted pair wires...

In addition, the routes connected to the Intranet set the IP address of the LAN side (for example, 192.168.2.1), and then enable DHCP to allocate IP addresses (192.168.2.2 ~ The IP address range 192.168.2.255 has no relationship with the Intranet even if it conflicts, because the Internet of the machine under the route is generally invisible .), Then, set the wan ip address and MAC address of the route to your machine address. In this way, the PC under the route can connect to the Internet through the route.

If you want to connect the Internet to a machine under the route, you need to open a service in the route (enter http: // route address. If it is not at first, this is the route address, which is generally http: // 192.168.0.1 D-link is like this), and you can find it on the UI.
