How do different IP segments connect to the server? The company's server is in Building A, and a network cable is signed from there to the router in Building B, with different network segments.

According to your description, I now think of a set of structures that you might use, as follows:

A broadband cat in Building A is connected to the router in Building A. The network segment of Building A is a certain network segment, such as 192. 168.0.0/24 A. The router in Building B is connected to a network cable, which is connected to the WAN port of the router in Building B. Set dynamic IP to obtain the routing address of Building A. The network segment of the router in Building B is/kloc-.

With this address segment, your computer in Building B can access the server in Building A, including the * * * shared address. For example, the address of the server in Building A is 192. 168.0.2. All you have to do is type \\ 192. 168.0.2 into the computer in Building B. As for what you said about not visiting, I think you have a problem. If you really don't understand, you can change the connection mode, connect the line routed from Building A to the LAN port of Building B. Then turn off the DHCP of Building B and turn on the DHCP of Building A, so that Building B can get the address of Building A. ..
