I am looking for some help getting IPv6 configured properly on a Fedora 27 system. I have one system which was installed fresh with Fedora 27, that system is working properly, it receives both IPv4 and IPv6 addresses assigned by my router (running latest LEDE release). I have a second system which receives the expected IPv4 address but does not receive an IPv6 address.
I notice that on the working system NetworkManager shows two instances of dhcp client:
Some of questions.
What desktop are you using? The NetworkManager GUI displays are a bit different between KDE and GNOME.
Are you using the GUI to configure the interfaces or doing it manually?
I think the problem is that in your config file you have both
IPV6_AUTOCONF=yes
and
DHCPV6C=yes
I don't use DHCP for IPv6 in my network since Android devices can't use it. So, I manually configure IPv6 for systems where I want a "short" IPv6 address and they are "servers". For the other systems I just let them use the IPv6 native auto-discovery do its things.
I believe with both of those parameters defined the IPV6_AUTOCONF takes precedence and will prevent the dhcp-client from starting.
FWIW, using the GUI on KDE I could not force my config files to have both of those defined with "yes".
