@robi Feeling stupid right now, but i dont see a a list with interfaces when opening a terminal to the OpenVPN app.
In the logs of the WordPress App i saw an ipv6 ip which represented by local internet connections ipv6. This seems to be caused due to a misconfiguration in OpenVPN after activating ipv6 for cloudron. However now a can see my private ipv4 address in the logs. Not the internal one of the VPN or the external one of the server.
I assumed i can see the external ip of the server in the logs and simply whitelist that. To achieve this do i have to work with the Forwarded header? Is there an example somewhere? I am a bit lost to be honest.
