So I have a router with a server connected. Also connected to that router is a switch, and on that switch is a Client. My problem is that if I change the ARP entry of the server to a different (incorrect) MAC, traffic still flows fine. Shouldn't an incorrect ARP entry in the router break the flow of traffic? The server and client are on different subnets.
The client is at 126.96.36.199/24, The server is at 188.8.131.52/24
My command was like arp ip.ip.ip.ip 0123.4567.89ab arpa
I must be missing something dumb here. What gives?
