[Bug 1434525] Re: Router solicitation blocked, makes network-manager complain
Could you help me how to solve this issue, plese?
I'm using Debian 8.1 stable and ipv6 support is disabled either in
a) /etc/default/ufw
IPV6=no
b) /etc/sysctl.conf
net.ipv6.conf.all.disable_ipv6 = 1
net.ipv6.conf.default.disable_ipv6 = 1
net.ipv6.conf.lo.disable_ipv6 = 1
net.ipv6.conf.eth0.disable_ipv6 = 1
Therefore I can not apply this:
http://askubuntu.com/questions/596278/what-is-network-manager-trying-to-do-with-rdisc
sudo ufw allow to ff02::2
it says: "ERROR: IPv6 support not enabled"
Is the only one solution to compile ufw using patch in #2?
Thanks!

Maybe /etc/ufw/before6.rules should be adjusted ? (or maybe it's a bug
in Network-manager?)
