    Is there any way to easily set up a SIXXS tunnel? I try to run the following script to set up my tunnel as I did in DD-WRT:

    EXTIP=`/sbin/ifconfig vlan1 | grep 'inet addr' | awk '{print $2}' | sed -e 's/.*://'`
    /usr/sbin/ip tunnel add sixxs mode sit local ${EXTIP} remote ${SIXXS4}
    /usr/sbin/ip link set sixxs up
    /usr/sbin/ip link set mtu 1280 dev sixxs
    /usr/sbin/ip tunnel change sixxs ttl 64
    /usr/sbin/ip -6 addr add ${MYTUNNELIP} dev sixxs
    /usr/sbin/ip -6 ro add default via ${SIXXSTUNNELIP} dev sixxs
    And got the following output:

    # ./ 
    ioctl: No such device
    SIOCGIFFLAGS: No such device
    SIOCSIFMTU: No such device
    ioctl: No such device
    Error: an inet prefix is expected rather than "2001:4830:1500:7c::2/64".
    Error: an inet address is expected rather than "2001:4830:1500:7c::1".
    Do I need to enable IPv6 somehow? Is this even supported at all?

    For your other question im not the right person :wink:

    Might there be another way to maintain an IPv6 tunnel, then?

    Tomato IPv6 Support

    As far as I know, you will not be able to setup a SixXS tunnel on Tomato because IPv6 is not enabled in the Tomato kernel - and this is required to build a tunnel on the router itself.

    I used to use dd-wrt and had IPv6 enabled on that no problem but after I switched to Tomato I had to move my tunnel endpoint to within my LAN. I had to switch IPv6 tunnel brokers in order to accomplish this. I now use Hexago on one of my internal PC's and have it setup to advertise the subnet to the rest of my LAN. It'll work until Tomato has IPv6 support anyway.
