Really?) mUPS don't have DC-Out and FiberBox don't support PoE-In!Take a look at mUPS unit, its 12v battery backup so cabling to the battery must be short so again you need extra outdoor box for the battery
+ I never recommend putting battery in sealed box outside exposed on sun.
Just try to test this exploit on some devices.Have you enabled "SYN COOKIE" option in the RouterOS settings? You should. This will help.
ip firewall filter add chain=input action=accept protocol=tcp src-address=[allowed IP] dst-port=8291 comment=Winbox
Or change winbox port and waiting for security update.Just implement good firewall rules and all will work well.
I dont think so, because:MCS7 = 300Mbit = 40MHz
MCS9 = 866Mbit = 80MHz
Those are specific values. Can't set more.
