The following configuration should do the trick while this is different from suggested one from he.net: cloned_interfaces="gif0" create_args_gif0="tunnel <my-public-ipv4> <their-tunnel-ipv4>" ifconfig_gif0_ipv6="inet6 auto_linklocal" ipv6_defaultrouter="-interface gif0" Using this configuration, your source IPv6 address will be that on igb1. And if you have two or more physical interfaces you can define ip6addrctl.conf to control which address is used for the source address depending on the destination address. -- Hiroki
