Hi, i just installed mikrotik a few days ago. Today i see following error in log using winbox:

Is someone trying to connect my router from WAN? Is my network secure?

Yes, likely.

Nobody knows. :slight_smile: It may only be considered secure when configured properly. So please address this question to a person who configured your device.
