Debian Bookworm -> Trixie upgrade - systcl troubles
I’ve been running Debian on a PCengine apu2 for a very long time now. I’ve upgraded it from buster to bullseye to bookworm and now.. to trixie.
The upgrade process went well, but i had one issue after rebooting the system - masquerading (or ip forwarding) didn’t work anymore. I invested time in setting up nft for my firewall, so I initially expected some issues there. The /etc/nftables.conf file was applied correctly at startup though.
