Why don’t you use Mikrotik’s own BTH ? It’s a secure way of remote connection to your device. It’s VPN connection using Wireguard. You can use their BTH app or Wireguard app on a PC.

And what are you trying to achieve is a great way to get hacked, you basically want to allow all IP addresses to access your router…
