[Pkg-utopia-maintainers] Bug#756534: network-manager: IPv6 hop limit set to 0

[Yin]

I can confirm I'm getting the same issue. (Running Jessie/Sid, with 
network-manager Version: 0.9.4.0-10)

It appears that network manager will directly change the sysctl values 
like thus:

# sysctl -A |grep -i hop_limit
net.ipv6.conf.all.hop_limit = 64
net.ipv6.conf.default.hop_limit = 64
net.ipv6.conf.eth0.hop_limit = 0
net.ipv6.conf.lo.hop_limit = 64
net.ipv6.conf.wlan0.hop_limit = 0

Once reset using a script or sysctl -w directly, once the interface is 
brought back up (unplugged-replugged or wifi reconnect) it will reset 
the value from 64 (or whatever) back to 0

I've had a look through the RedHat/Gnome NetworkManager git tree, but 
cannot see any fix for this as yet. I have been unable to confirm if its 
an issue with their source or if its a debian patch that has introduced 
this.
