I'm not seeing any outbound IPv6 traffic from my CentOS 7 box on the WAN interface. I do see RA's emitting from the LAN interface, from radvd. Is there some setting in NM tells it to send solicitations? Is there some way to push one manually?
What's in /etc/sysconfig/network-scripts/ifcfg-<name>? I wonder if you have IPv6 disabled.
I'm not using a "regular" (CentOS, Fedora, etc.) Linux as a gateway; I have OpenWRT on a dedicated box. I couldn't find a way to handle the prefix delegation with the typical desktop/server tools (but it has been a while since I looked). OpenWRT has their own daemon for that.
However, my local systems are all sending RA solicitations and getting DHCPv6-assigned addresses with NetworkManager (which matches the first steps of what you need on the WAN, just not the prefix delegation).
