Uhhhh…that is…not how you do that. Especially if you’re describing routing out from a container to an edge device and back into your host machine instead of using bridged network or another virtual router on the host.

Like if you absolutely had to have a segmented network between hosts a la datacenter/cloud, you’d still create a virtual fabric or SDLAN/WAN to connect them, and that’s like going WAY out of your way.

Wireguard for this purpose makes even less sense.
