NAT + Firewall question

Normale case: I host a minecraft server on port 25565 on my PC which is assigned: 192.168.0.100 as a local IP.

If I want other users to join I go into my Router and portforward 192.168.0.100 & port 25565.

When I disable my firewall however people can still join my server, but how does my router know it has to forward the traffic to 192.168.0.100. Lets say 192.168.0.101 also has a minecraft server running on port 25565. What would happen?

Isn't that the entire point of NAT?
