Have router RouterOS v6.42.1 (stable) and model:RB3011UiAS-RM following instructions from: http://www.icafemenu.com/how-to-port-forward-in-mikrotik-router.htm, I configured portforwarding for ssh service which has been working till 3rd Jun 2018. Currently am denied access on ssh. Have even tried to reconfigure, it still doesn’t work.
