Wireguard Host to Net

Hello, I’m revisiting this topic because I’ve figured it out. I have the following setup: Fritz→Ipfire

Behind the Ipfire is a VM with Wireguard, which also works great. Now I want to use this on the Ipfire as well. So I set up a forwarding with another port to Ipfire on the Fitz. Now I create a configuration in Ipfire with a network that differs from OpenVPN, the previous Wireguard, and the local network.

I put the QR code on an iPad, but it doesn’t work. No data is transferred, and Ipfire does not show that a connection has been established. In the iPad log, I can see that the connection is being attempted.→ handshake did not complete after 5 seconds → sending handshake initiation

Does anyone have any idea what could be causing this or where I’m going wrong?
