On the wired network, same problem, IPv6 is fine (no NAT64 on the
wired, it seems), IPv4... I don't even get an address:

% ip route show
192.168.122.0/24 dev virbr0  proto kernel  scope link  src 192.168.122.1 

(virbr0 is an interface to my virtual machines, not the network)

% ip -6 route show
2001:67c:370:128::/64 dev eth0  proto kernel  metric 256  expires 2591998sec
fe80::/64 dev eth0  proto kernel  metric 256 
default via fe80::128:1 dev eth0  proto static  metric 1
