I followed the steps here to set-up a local Wireguard connection on my Mac. I can confirm that running dig +short txt _apps.internal @fdaa:0:455a::3 does indeed work (and have run some other commands).
I’m now attempting to connect to the Wireguard network in a local Docker container running via Docker for Mac. How can I do that?
You’ll need to make sure Docker is setup to use IPv6, at the very least. The simplest way to test this is to run a one off image and try pinging. Something like:
docker run --rm -ti wbitt/network-multitool /bin/bash
Then ping one of the Fly.io IPv6 addresses you have access to over wireguard. They should all response.
