Description Philipp Hahn univentionstaff 2018-03-16 13:52:11 CET
# grep 6 /etc/network/interfaces
iface eth0 inet6 dhcp

or better switch everything over to /etc/systemd/network/

<man:systemd-networkd(8)>
<man:systemd.link(5)>
<man:systemd.network(5)>
<man:systemd.netdev(5)>

Just a quick note, at least dhclient needs an additional iptables rule to work with IPv6:
'''
ip6tables --wait -A INPUT -p udp -s fe80::/10 --sport 547 -d fe80::/10 --dport 546 -j ACCEPT
'''

And because I was puzzled why we don't need a similar rule for IPv4: dhclient uses a raw socket for IPv4 which side steps all iptables rules.
