Hello dear people.
I have A LXC with a Zerotier-Controller set up, and also installed Zerotier on the Proxmox Host.
Proxmox Host > ZT Central, which my remote machine (normal ARCH Desktop) is connected to. On ZT central I have set up a Managed Route to the LXC IP range, that goes via Proxmox's ZTC (Zerotier Central) IP.

How I think it works:
Remote location Desktop sent request for 10.10.10.x (LXC) > ZTC: "ok I'll push that over to [Proxmox ZTC IP]" > Desktop can connect to LXC.

Other Info: I made a Masquerade on the LXC network range, so 10.10.10.1 is Proxmox (gateway for the LXC).

Now, my problem:
My LXC Containers have no internet connection. I cannot update any packages (That might also contribute to my second problem, of my friends getting a "Time Out" when they try to use my Selfhosted ZT IP (of my Arch Desktop) to connect to my minecraft world).
