I use the Mikrotik for my hotspots. I see a user with a particular MAC address has been trying to login to my routerboard through winbox using the admin account. I do not enable the admin account, but I want to know, if there is a way to block access to my services to a particular MAC address?
Block this MAC in firewall input chain
/ip firewall filter add action=drop chain=input src-mac-address=AA:AA:AA:AA:AA:AA
