Shouldn’t be a simpler ipv6 discovery. Currently I have to “hot” connect (connect after I get the little network sign on the bar) the Need(ipv6)AddressVM with the firewall VM and get it from network Edit connection menu (eui64 128 eui64). If it was my choice it would be displayed in the Qubes Manager. Anything simpler that works also for NonQubes HVMs would be appreciated.
