Wrong IP able to communicate

RouterOS General
1

I have a CCR and a single network (subnet) connected to each port. Each port is assigned a IP making it the gateway for the network on that port. On accident, I connected a laptop that had a IP that was from a network that resides on a different port on the CCR:
CCR-Port 1. 10.0.0.1
CCR-Port 2 10.0.1.1
Laptop - 10.0.1.2 gateway 10.0.1.1 connected to Port 1.

I was surprised to find that this worked. I was able to ping the 10.0.0.1 network and was able to get out on the internet. The assigned gateway on the laptop should not have been found/reachable because it was connected to the wrong port. Am I missing something here?

maybe port1 & port2 in the same group

master and slave or have the same master port

The CCR I have does not have switching ports. The only way to do that with the CCR is through bridging and I have no bridges.

Maybe you have proxy arp enabled on the interface?

5

I just have Arp enabled on that port, no proxy.

Please post a /export of your config.
