I have Hivemanager on-prem , managing branch router BR200-WP, tunnel up and running , I can update branch router etc. Now I close udp port 12222 and still able to update branch router ....? So what's that management on udp port 12222 is needed for , only register new devices ?
But I have ONLY port 12222 opened on VHM , using console on BR I can still see 'Server destination Port: 12222' and from VHM I can do i.e. diagnostic-> show version etc . My point is not to fix (this is lab only) , but understand how it works
