No wireless IPv6 connectivity for subnet
![[nl]](/s/countries/nl.gif) Carmen Sandiego on Tuesday, 05 April 2011 21:42:08
I've setup a tunnel on an Ubuntu machine, which should route my IPv6 subnet behind it and anounces it via radvd. When I attach another machine directly to the ethernet switch everything works fine. When i go wireless with the machine, it does receive the global IPv6 address, but no IPv6 connectivity at all. Also not local. The wireless accesspoint (Fritzbox) contains the switch, where the IPv6 tunnel is made on a direct connected Ubuntu machine. So the problem is in the wireless part, but what van it be?
Setting up an IPv6 tunnel wirelessly does work, so it looks like de AP kind of blocks IPv6, but strangely i DO get a global ipv6 address...It's driving me crazy.. :-(

I have a similar setup (Linux box for tunnel distro, routing etc) and a Fritz!box 7270 solely for the wireless and voice (it can do IPv6 too, but no proper firewalling, no ability to configure which prefix to use etc etc, thus not used). This works like a charm, thus it can work.
Check your neighbor tables (ip -6 nei sho) if those can be resolved.
Sometimes one needs to enable PROMISC or ALLMULTI on an interface.
For the rest wireshark can tell you what happens or not.

Hello Jeroen,
Thanks for replying. I've a Fritz!box 7170 and don't have an option for setting it to PROMISC or ALLMULTI. Anyway i looked via tcpdump to supply the forum with the information i see exactly (I saw icmp ping going out and not come in on the other side) and now as the Dutch say: my wooden shoe breaks! In other words it's working at the moment, but i've to investigate more to see if it's stable.
Thanks anyway. I'll get a FRITZ!Box 7340 in 2 weeks, so maybe that will also work better, cause it seems to support ipv6 and might be able to use the Fritzbox for the tunnel instead of Linux/AICCU
Cheers,
Sjoerd

The moment you do a tcpdump (unless you use the -p option) it will set that interface into PROMISC mode.... thus that might be the solution to your problem.
Technically a Fritz!Box does run Linux with quite a few weird changes, AVM did make their own TIC & heartbeat implementation apparently though thus it is not AICCU. Do note that Fritz!Box does not support AYIYA (which it in effect does not need as is sitting on the public IP address) and there are quite a few limitations still to how subnets can be routed; for most people it works fine though.
