How to administrate when all services are stopped

Hello,
While testing impact of services started on NAT rules I have deactivated all services (ftp, telnet, ssh, winbox, web) using winbox before to realize that without them I can’t connect to the router.
Is there a way to reactivate them without breaking the current configuration?

Use the serial port if your router has one.

It has no serial port.

Have you tried using Winbox to the MAC address?

That’s the only possible backdoor I can think of. Otherwise, you may just have to reinitialize the board and lose your config.

Could try logging in via neighbor if there is another MT unit connected to it and neighbor discovery is turned on.

Using Winbox on MAC address allowed me to connect and I was able to reactivate the winbox service.
Thanks!
