hello,

i have this kind of configuration :

192.168.1.0/24 -- A (2001:7a8:6cd1::caca) 
                  |
               INTERNET
                  |
192.168.2.0/24 -- B (2001:7a8:b138::caca)

i want to make my ipv4 in ipv6 tunnel configured at boot time. i added :

rc.conf(A)

gifconfig_gif0="2001:7a8:6cd1::caca 2001:7a8:b138::caca"
ifconfig_gif0="inet 192.168.1.1 192.168.2.253 netmask 0xffffffff"
static_routes="vpn0"
route_vpn0="192.168.2.0 192.168.2.253"

rc.conf(B)

gif_interfaces="gif0"
gifconfig_gif0="inet6 tunnel 2001:7a8:b138::caca 2001:7a8:6cd1::caca"
ifconfig_gif0="inet 192.168.2.253 192.168.1.1 netmask 0xfffffff"
static_routes="vpn0"
route_vpn0="192.168.1.0 192.168.1.1"

it's working well, congratulations to dev ! but, here is my problem
(/etc/network.subr) :

gif_up() {
        case ${gif_interfaces} in
        [Nn][Oo] | '')
                ;;
        *)
                for i in ${gif_interfaces}; do
                        eval peers=\$gifconfig_$i
                        case ${peers} in
                        '')
                                continue
                                ;;
                        *)
                                ifconfig $i create >/dev/null 2>&1
                                ifconfig $i tunnel ${peers}
                                ifconfig $i up
                                ;;
                        esac
                done
                ;;
        esac
}

it wont create a tunnel with ipv6 as transport layer. it should be able
to exec a "ifconfig $i inet6 tunnel ${peers}". is it an unhandled case ?
did i miss something ?

thanks for your answer.
