If my network’s configured incorrectly, how are my computers communicating?
I have a question regarding communication within a local network. Please correct me If I am wrong: If there are two computers in a local network, Computer (A) and Computer(B), and if (A) wants to communicate with (B) or vice versa, then the request first strikes the router’s LAN interface, right? My question is that [...]
