User Manager and Multiple Hotspot from different location

Hi, I’m tring to figure out how to setup a central User Manager with miltiple Hotspot from different location. I’ll give you an exemple, I have my main office in city 1 with the Mikrotik UserManager installed, now I want to connect my first Hotspot in city 2, that’s mean the only communication we have is by Internet perhaps I think I have to open the radius ports for Internet on my Mikrotik city 1 if I’m right ??? or it’s already setup when I installed Usermanager ?

After some tests I think the problem is with the Firewall, No port 80 or radius port are accessible, but I’m not sure with rule I have to create to enable it.
