Locked out by firewall rules

While applying my firewall rules to a RB150, I forgot to assign my DROP input rules to an interface. Now I cannot login to any interface. Not even the serial interface to undo or reset the RB150. Can anyone help?

I am sorry if this has been asked and answered, I spend several hours searching this forum and the web for an answer.

Download neighbor viewer and use MAC telnet.

If you aren’t familiar with the CLI just do a system → reset to reset to defaults.

winbox also supports connection with MAC address. Firewall only affects IP level communications. Also of course serial console or keyboard+monitor.

And if all else fails you can manually reset it i beleive, using the s- reset on the board, shorting the 2 prongs will reset to factory settings… Just incase you can’t Use MAC to login to your board. -Jordan

I found the problem, when I setup the serial connection, under Flow Control I had RTS/CTS selected and so the serial connection would display but not let me type. So the correct answer is setup the serial connection correctly.
Baud= 115200
Data bits= 8
Parity= None
Stop bits= 1
Under Flow Control make sure no options are checked.

All the answers provided were correct. There were multiple fixes for your problem.

I thank everyone for their reply.
