I upgraded my RB750Gr3 to v6.41 today. I see there's major change in port configuration, so I did backup. However after upgrade, I see everything works fine except all managerial access. Winbox, SSH, Telnet, all seems to be no longer binding to any port.
My questions is, 1) is there any method available to me to regain access? And 2) suppose I need to factory reset, is it possible for me to restore my backup and fix the issue?
Thank you and happy holidays!
