Remote WinBox

Hello !

I have activated VPN (cloud) on my Chateau 12. The service for WinBox on port 8291 has also started. In my firewall I added the option Chain = Input, Protocol = TCP, DST Port = 8269.
When i start the VPN on my iphone and go into the browser to open my Router Interface (192.168.88.1) the RouterOs Login Screen would open and stopt that !??
I cant me login.

Have i make a wrong setting ?

This is certainly not the right IP, this IP is only from your actual LAN.
See what is the gateway IP in your phone VPN information page.

What am I missing here. Is there some sort of automated VPN setup to reach ones router via winbox remotely.
Please clarify as up to now I thought one had to use something like IKEv2 VPN to connect like from my iphone and then use the MT app to configure the router via the vpn tunnel.
