Troubles getting WireGuard to work

[sven_gramer]

Hello together!

I would highly appreciate some help since I have troubles to get my wireguard to work. I am fairly new to networking.

Here is my current homenetwork setup:

INTERNET <------> Huawei LTE Router <----BRIDGE MODUS without firewall ----> OPNense APU4d4 Router <---- > Homenetwork


If I connect from my Phone in the same network WLAN to Wireguard it works without problems as long as I connect to the WAN IP shown belown. As soon as I try to use my phones lte network or if I try to use my public facing IP it doesn't connect anymore. I tried to monitor all traffic on my opnsense with the wireguard port 51820, however if I try to connect to the public facing IP or the the WAN via LTE i don't see a single packet.

My WAN IP is: 10.45.XX.XX
And my public facing IP is:  194.230.XXX.XXX

I setup all necessary NAT and Firewall rules as shown in the guides in the official docs. I have no clue what I am doing wrong. A few months ago I tried to setup openVPN where I ran in a very similar problem.

Can you paste the client config of the device you are attempting to connect from?

Maybe this guide can help you.
If you go through the steps and check with your own config:
