Dual LAN cards for dual LAN communication

1. Store the relevant data of each post computer on a server, and then use the server as a client, and then upload it to the final server;

   • After using dual network cards, both network segments can transfer data to this relay server;
   • This has a drawback. It can only realize the function of data upload, but the computer (client) of each post cannot directly access the server (such as the function of downloading data, etc.) .
   • This is actually unnecessary, it seems redundant, and the transit server seems to be too wasteful of resources, and it itself acts as a storage.

2. All post computers are upgraded to 2 network cards, so that the client / server can be in a local area network.

   • After using dual network cards, it is convenient to add a static route to the server!
   • Each post computer (client) can directly access the server .

3. An experiment is also needed to observe whether the two network segments can access the server program normally when the server is set up with dual network cards and the server program is running. (Personally think it should be feasible, after all, it has been able to communicate according to ip)
