This is a relatively new way of doing things, not every tool is going to
support it.

What exactly are you trying to accomplish by doing this? In my mind you can
simply have *one* wg tunnel on the LXC host machine and use routed veth
networking to connect the containers to this uplink, but I'm probably
missing something.

I'm not sure I've understood your current setup. Could you make your
explaination a bit more concrete? Wg configs snippets from the Host and
container would be helpful.

Sounds nice but you'll want to talk to the LXC project instead of WireGuard
if getting that supported is your goal.
