Re: EoIP between 2 RBs w/ dynamic IP on one side

you can make in a central place PPPtP server and this sites with dynamic IP connect via ppptp to the main and then over the PPPtP links make eoip tunnel - it worked for me just fine

Re: RB-912 outdoor

OK but this box in this situation doesn't have sense - UBNT makes cables to their antennas. if I have to play with R-PSMA i prefer make bigger alubox with N-connector and put a standard 912UAG in it. I use only RF 300 cable and it's too thick to make such a short patchcords. Another thing that r-psm...

Re: RB-912 outdoor

What do you mean with "chains are reversed"? How can they be 'reversed'? In SXT chain 0 is Horizontal but you can't connect to ubnt antenna with leds on visible side because ubnt has Horizontal on the ritght side and mikrotik on the left. It would be nice if ubnt connectors and mounting place would...

Re: RB-912 outdoor

HI, i have a question did anyone has a solution to fit RB912UAG-5HPnD-OUT on ubiquiti antennas ?
Mikrotik do you plan to have such a mounting bracketr ? I though it would ideally fit into ubnt antennas but it doesn't ,and chains are reversed.
