I am new to ipv6 so everything is a learning experience for me. Does ipv6 have a range of non-public routeable ipv4 address that are reserved for LAN use like 10.0.0.0/8 is for ipv4? Do any of the 3 freebsd firewalls have ability to do ipv6 NAT? Can the default dhcp client handle ipv6? On my host I run ipfilter firewall, I have done nothing to enable ipv6, but the daily security email shows a list of ipv6 denied packets. Does this mean that ipv6 packets are flowing freely on the public internet? My current goal is to configure ipv6 to work only between my gateway and LAN nodes. Have been unable to find example on how to accomplish this. Can anyone point me to such documentation. Thanks in advance.
