I have not changed my setup but since yesterday I can no longer use internet when wireguard is active, neither when in my home plan nor when outside using my mobile internet.
systemctl status wg-quick@wg0.servic doesn’t show errors and is active yet the wireguard app on my phone is looping at the handshake initialisation stage as soon as I activate it.
The only thing I can think is pihole as I did update it couple of days ago. But no settings were changes, permit all origins is still active.
Ddns is set up correctly and works. I can access my pi via ddns when outside of my home network when wireguard is not active.
As soon as I activate, wireguard on my phone, I don’t have internet anymore.
Any ideas how to tackle this? I am out of ideas what to check.
you would need to check if a handshake is done between server and client. On client side, you should have a log within Wireguard App and on server side you can use wg command.
Usually these kind of issues are related to incorrect DDNS settings or wrong port forwarding on router.
I do have internet access and ddns does work as well as per dietpi-ddns.
But as soon as I activate wireguard, I don’t have internet connection anymore.
Maybe my conclusion is wrong but my router’s IP starts with 100. now which indicates CG nat, or?
I believe (not sure) that before I had a 85. or 95. ip address and my setup and all settings that come with it was working without issues even with wireguard active.
‘no external ipv4 (guarantee) for private customers as per our terms and conditions, you were just lucky in the past’ (which was for the last 4+ years, but well…now I am unlucky going forward)
