Thanks for replying! That eye thing helps; tells me that at least the config file gets imported correctly. That being said, the default IPv4-only for WireGuard in Unraid means that if I set it to IPv6/IPv4, it'll lose most of the imported configuration. The UI's also unclear about my end's public IP address being optional; I know in the other WireGuard setup I maintain (traditional, not Subspace), I don't ever have to worry about the home user IPs.
Subspace-generated WireGuard config...
