I need help

Hello,
Tonight I wanted to set up DMZ on my Mikrotik router, I found on the internet this command:

/ip fi n a ch=dstnat pr=tcp dst-p=1-65535 ac=dst-nat to-a=192.168.1.131 to-p=1-65535

(192.168.1.131 is IP address of my PC)

I run this command in the terminal and from that moment my internet does not work and I can not connect to the Mikrotik using Winbox (from any device).
Does anyone know how to fix it without reset to factory settings.

Thanks
