Found another problem with the upgrade of my server to trixie -- IP forwarding no longer worked.

This really was a #systemd issue, caused by the use of systemd-sysctl. The upgrade renamed /etc/sysctl.conf so that it no longer took effect; I had to create a file in /etc/sysctl.d/ with the relevant setting.

I think this should have been in the #Debian wiki, if not the #ReleaseNotes

#trixie #IPForwarding

Dropped a new Blogpost https://tinfoil-hat.net/posts/proxmox-server-vps-single-ip/

Please tell me what you think about it :-)
