I am using MikroTik 450G and recently i am having trouble with my network. How can i protect by using duplicate MAC address from client pc??? Network users are putting MAC address of another pc and using internet. How can i identify a real MAC address and FAKE MAC address??? I am beginner user for MikroTik so please can i have step by step guide???
The best way is prevent duplicate mac address at the start-> managed switches with port security is the best option
