NM needs to put the interface UP so it can reliably monitor the link state. But that was turning ipv6 addr auto-config on and was considered a security issue and thus NM started disabling ipv6 on such (non-configured via NM but monitored) interface to avoid the address auto-configuration from happening, yet causing this. The fix (to be able to bring it up without ipv6 address autoconfig) needed kernel & NM patches and show be available on 7.0.z very soon. > This does, however, leave me somewhat confused as to how you claimed there > was a fc00::1001 address on there and you were adding the additional > address when you saw the refused message... Such address was on the host, no? Cheers, Marcelo
