Hi,
I’m trying to use a couple of Mikrotik Metal 52 ac as a point to point connection.
I’ve different problems:
1: once I link bridge to ethernet port I lost the device and I cannot find it in winBox
2: I don’t know if the list of operation followed is correct,I tried to use this video https://www.youtube.com/watch?v=Gc366icqxx8

Thanks!
