Yes I know how to use the address List in the firewall setting but how I drop all the others IP in my network? I need to see how to do it, I know how to do it in TPLINK equitment and Ubiquiti too, but in Mikrotik i dont know, I’m using a Wireless Antena, LHG5… So I want that any one else than me, have access to the Antena, I have it configure it as a CPE to internet…
