Small Matrix Instance (for Bridging under alpine lxc)
Nextcloud (for phone data under debian lxc)
Jellyfin (for old CD rips under debian lxc)
All of this is under Proxmox VE
I also am a Sysadmin for Project Segfault (projectsegfau.lt/instances), where we host a lot of other stuff :)
Look into getting a VPS to proxy things through using either wireguard+DNAT, rathole or SSH tunneling.
