Yes that would be possible, but do note that I am using a non-documented / supported setup. I have no idea what would happen if it is not a good thing to do and might cause harm.

I have placed my main ip in the router subnet itself, and created routing with that. FreeBSD cannot find the gateway otherwise, on Linux this seems to work but I couldn’t find a way to do it differently. So in the light of their ‘master IP and assigned routed subnet’ I did the same for IPv6:

ipv6_enable=”YES”
ipv6_ifconfig_em0=”2a01:4f8:xx:xxxx::2/59″
ipv6_defaultrouter=”2a01:4f8:xx:xxxx::1″
ipv6_ifconfig_em0_alias0=”2a01:4f8:xx:xxxY::2/64″

and a range of additional IP’s in that regard. Notice that the last alias pasted has an Y on the end, stating that this is from my assigned subnet, where the xxxx network is the router’s network.

Hope this helps and doesnt break anything

i am sure they will be available already or soon on the mirrors. tagging something means that new builds will have the uname that goes along. so please have another look in a day if they are not there yet.
