Huge bug: Mikrotik allows adding overlapping networks.

@ners

Are you saying that assigning 10.7.19.89/29 (the same IP address) to two different interfaces and having different hosts on these two interfaces in the same network is a perfectly valid configuration?

Even better, you can have hosts with exactly the same address in all those networks! Is it normal? Nope. But it can be useful sometimes. Ok, this one may be going to extreme.

But for example VPN clients using smaller subnet from LAN (e.g. /28 when LAN is /24) and then with help of proxy ARP appearing to be part of that bigger LAN is perfectly normal config used by many people.
