Unable to connect to Microtik router (2011UAS-2HnD-IN)

I was working with Firewall filters and NAT in order to configure VPN on the device in question. Once done, I closed winbox, and after a while I’ve tried to connect, however I could not reach the router (Through winbox, web GUI or even ping), however traffic was flowing through it; internet was available.

Can anyone suggest a way to allow me to connect to the device without resetting and loosing the configuration ?

Thanks in advance.

Have you tried to connect by mac address with WinBox? (The Neighbors tab?) Mac address isn’t routed so make sure you’re plugged into the LAN bridge.

Other option is if you have a Cisco style RJ45-to-Serial port cable and a serial port you can get to the CLI via serial terminal.
