Hi All,
I am running Virtual Machine Manager (3.2.0) on debian 11 running a
gnome desktop.
I have one VM with a NAT NIC as I practically only have a wifi interface
available on the host (need to use wifi rather than wired).
The VM gets both an ip4 and ip6 address assigned.
192.168.122.37
and
fe80::f43d:2a35:aa97:cd3e
and made sure it has no firewall running
@VM:~$ ufw status
Status: inactive
I created a hostname rtop-udev in the local network router to point to
fe80::f43d:2a35:aa97:cd3e
@host:~$ nslookup rtop-udev
Server: 10.4.0.254
Address: 10.4.0.254#53
Non-authoritative answer:
Name: rtop-udev.lan
Address: fe80::f43d:2a35:aa97:cd3e
The host also has both an ip4 and ip6 address
@host:~$ ip a

I can ping the VM fine using ip4
@host:~$ ping 192.168.122.37
PING 192.168.122.37 (192.168.122.37) 56(84) bytes of data.
64 bytes from 192.168.122.37: icmp_seq=1 ttl=64 time=0.459 ms
But pinging with ip6 I am somehow doing something wrong. I tried;
@host:~$ ping fe80::f43d:2a35:aa97:cd3e
PING fe80::f43d:2a35:aa97:cd3e(fe80::f43d:2a35:aa97:cd3e) 56 data bytes

What must I do to enable access from the host to the VM using ip6?
