    Good afternoon,

    I'm having Trouble Setting up my enviroment for IPv6 Access at home.

    Current Setup:
    Tunnelbroker HE /48 -> R1 with br0 (1st /64) +br 1 (2nd /64) -> R2 (DHCPv6 Prefix Delegation /64)
    So with R1 I initiate a HE IPv6 Tunnel with /48 prefix.
    On br0 (R1) I use the first /64 subnet for IPv6 Services - all fine!
    On br1 (R1) I use the second /64 subnet for IPv6 Services - here Comes the Trouble:
    as soon as Clients e.g. Win7 Client is connected, he gets a IPv6 advertised, all fine BUT
    I want to use a DMZ Setup with second router here. So I Setup R2 with DHCPv6 Prefix Delegation /64

    Now from R2 I can ping google.com's IPv6 address without any issues. But my Clients behind R2 dont get any IPv6 addresses advertised.
    Ifconfig of R2 Shows Scope:Global IPv6 address on vlan2 but no Scope:Global address for br0 of R2 --> dnsmasq running on R2 does no RA/DHCPv6.

    So how is the correct Setup on R2 to somehow "Bypass" ipv6 from R1's br1? I thought Prefix Delegation is the correct way to use it here.

    Due I'm not grown up with IPv6 I'm sorry if I did a Basic misunderstanding of that Story.
    Any help is appreciated!

    EDIT: Both devices: R1&R2: Asus RT-N66U on Shibby RT-AC v115

    Your setup is rather elaborate, how about trying a simpler approach?

    On R1 all you need is a "6in4 Static Tunnel" using your 1st /64
    On R2 use "Other (Manual Configuration)" with your 2nd /64 and vlan2 as WAN gateway
    On R2 add a default route to R1 (ff00::, "1st /64", 8, 256, vlan2)

    I solved my Trouble with using "Manual configuration" -> Using 2nd /49 for R1->R2 Connection and on R2 using last /64 available in 2nd /49.
    Afterwards i've set a static route on R1 pointing to R2 /64's net.

    My head is Smoking... but... Its working :)
