When I'm with an IPv4-only machine with RAC (client) installed and I try connecting to an IPv6-only RAG (gateway), I get a message that I am successfully connected but there's acutally no connection made (this can be confirmed by running wg show
in the terminal; no wireguard interface is created).
SOLUTION
========
This is a known limitation and unfortunaately, there is currently no released fix for this. Ensure you are connecting to a gateway with a compatible IP version as your client machine.
