Every time I install OpenVPN on the raspberry PI 3 B+ it bricks my freedombox. I am willing to pay a bounty to get this working or even better WireGuard.
The OpenVPN works from my Android phone till freedombox reboots. Then it’s bricked.
OpenVPN making firewall inaccessible was a problem with firewalld in Debian. A work around was implemented in FreedomBox version 19.2. Could you check if the version you tried is equal or newer. Please note that if you are installing Buster, then version available there is 19.1
Other that this issue (needing version 19.2 for fix) there are no known problems with OpenVPN. It has been tested multiple times to work in 19.2 and in Pinoeer edition images.
@mray, The original post is about setting up a VPN client manually which we didn’t implement yet.
