Hello! There was a problem with the disappearance of remote access to multipoint, after a firmware update to version 6.31: some time lost access via Telnet VinBoks and, at the same address multipoint pinged and it generally works. It helps only power off. After some time, access is lost again. I do downgrade to 6.30.2 - no problem. Board is RB912UAG-5HPnD (mipsbe).
