I have 2 RB1100 tik routers that I want to access in the same zerotier network. With a new network on the Zerotier central, I would copy the network ID and add a zerotier interface on router 1. Rouer node ID shows up on Central and gets accepted online. When I add a new zerotier interface on the 2nd router, no new node comes up on the list and it just gets an OK status on Mikrotik but there is no node on central. Upon checking, both interfaces on Router 1 and Router 2 have the same MAC address.This explains why central sees registers only the first router and never the second.
Both zerotier interfaces was created from the menu of the Mikrotik routers (7.1.3)
