Full Tunnel doesnt work but Split is fine

[orchunchun]

All of a sudden the full tunnel doesnt work, i cant access the internet. Split tunnel still works fine without any issue.

Tested it by changing the allowed ip on the profile, also on different devices.

Was it ever working in the past? Not sure how long ago you followed the guide, but some changes regarding explicitly defining the MTU size in the client config, was a workaround the make full tunnel work.

Hi, I have a similar issue now.
So, I managed to make all this work on oracle cloud, just making a few changes where needed, and all worked perfectly fine for a while, be it split or full tunnel VPN. But then one day, when I upgraded the server from ubuntu 20.01 to 22.01, I just suddenly lost the full tunnel functionality for the VPN, even though split tunnel still works without issues.
Any clues on what may have caused this issue?

Hi. After problems with a local pi-hole installation on RPi, I was thinking of replacing it with a cloud installation as well. Then I found this blog post https://taurit.pl/pihole-in-the-cloud-nextdns/ advising to use NextDNS instead of pi-hole in the cloud. So I did and can recommend it. They offer a free tier to use.
