Hi,
currently I'm using gw6 + radvd on the fritzbox to have a global ipv6 on all my machines.

I would switch this (slowly) configuration to sixxs but I encountered some problems.. I already have a subscription to sixxs with a tunnel and a subnet, the tunnel works fine on my fritzbox. However I can't set up the subnet in any way and I haven't ipv6 connectivity on my computers
How I can do it?
 
You have to add /64 to the subnet prefix instead of /48 in your radvd.conf
 
in my sixxs page I've these info:
IPv6 Prefix 2001:1418:***:***::1/64
PoP IPv6 2001:1418:***:***::1
Your IPv6 2001:1418:***:***::2
Prefix 2001:1418:***::/48

In radvd config page:
IPv6 interface: lan
IPv6 address: 2001:1418:***:***::2/64
IPv6 prefix: 2001:1418:***::1/64

If I set in radvd config 2001:1418:***::1/48 my Linux machine says that it receive a wrong prefix. If I set 2001:1418:***::1/64 I get no errors and my machine get an ipv6 address but I can't ping any site (neither my fritz!)
 
IPv6 prefix: 2001:1418:***::1/64

Try removing the 1 in your prefix, so it will look like that:
Code:
IPv6 prefix: 2001:1418:***::/64

How does the routing table on your fritzbox look like?

Done.
I also removed /64 in IPv6 address (as in your howto)

Looks like there are some inet6 related routings missing in your tables.

very strange... if I ping an ipv6 from my fritzbox it works:

This means, your tunnel is up and working properly. But there seem to be a routing issue, because you cannot reach an ipv6 host from your internal LAN.
Your radvd settings should be fine now. Strange, that your routing is not working....:confused:
 
Similar problem with ipv6 and gw6

Hi forum,

I have a similar problem on my Fritz!Box fonwlan 7113 (UI). I've set up my freetz image with IPv6, gw6 and radvd from the actual trunk revision 3921.

So far:
IPv6 works on router. If I connect my Laptop through wlan0 I can't ping for example ipv6.google.com.
But if I set the route manually on my Laptop wlan0 device to go through the router to ::/0 then I can ping6 ipv6.google.com or www.kame.net and so on.

So we can concentrate on radvd. I guess I put in the prefixes and adresses correctly.
There is also another thing:
If I connect through eth0 (cable) then radvd gives this device (eth0 on my Laptop) the correct routes through route soliciaton or route advertising.

So I believe, the problem is something with the "lan" device which gets the router address.

I googled very hard and I could find a few similar cases, but also with no solution.

What could this be? And how can we solve this?

PS: I found out that the "lan" device on the box uses the same MAC address as the ethernet device to autoconfigure ff80::/64.
I tried to add an address to "lan" generated from the MAC of the wlan device of the box but this happended to change nothing. But maybe just because I don't know how to create the right address(es).

regards,
Daniel
 
Hi,

What is your lan / wlan configuration? Do you use bridged lan/wlan (same ip range) or do you split lan / wlan to separate ip ranges / routed segments in the AVM interface.

You can try to establish a layer 2 - bridge via brctl (if you have it in your freetz package), then the routing should work in both wlan and lan the same way.
