GL-AXT1800 Wireguard access home LAN

I’ve connected my Slate AX to public wifi and successfully set up a Wireguard VPN connection to my Draytek router at home.

When I visit a whatsmyip website it shows the IP of my internet connection at home.

I’ve also enabled the ‘Allow Remote Access LAN’ option in the settings of the Wireguard client.

However, I’m not able to connect to the devices on my home LAN.

To be sure the Wireguard configuration is correct, I’ve also imported the Wireguard config on my mobile phone and connected directly to my home LAN using the Wireguard client on my phone. In this case I can connect to the devices on my home LAN.

Any ideas on what I might be missing?

Maybe good to mention that the Slate AX is running with mosly default configuration such as LAN ip 192.168.8.x and my router home LAN runs on 10.2.90.x

Allowed IP’s in the Wireguard config is set to:
10.2.90.0/24, 0.0.0.0/0
