It is possible to reset all software configuration by short-circuiting the reset-hole during the power-up (see
ROS reset in layout diagram). No confirmation or passwords will be asked, so use with caution. This feature
can be disabled in the “system routerboard settings” menu by switching the “enable-jumper-reset”
parameter to “no”.
Specific answers require specific questions. When in doubt, post the output of "/ip address print detail", "/ip route print detail", "/interface print detail", "/ip firewall export", and an accurate network diagram.
