Hosts in LAN will be (firewalled) Internet availabe through IPv6 and can directly connect to other IPv6-Hosts in the Internet!
Global IPv6 Addresses are splitted in multiple Subnets per selected Interface.
If you want to use this solution you need the following howto(s) finished:
emerge net-misc/dhcpcd emerge net-misc/radvd

For starting the new service after system reboot you should add it to a runlevel with the following command(s):
rc-update add dhcpcd default rc-update add radvd default
