Double-NAT issues?

Hi,
i'm currently using a 3G Internet connection (Vodafone in Germany) and noticed, that my AICCU/SIXXS tunnel is not working anymore. I didn't changed anything on my tunnel endpoint, the only difference is, that i moved from DTAG DSL to Vodafone 3G, and that the latter is routing through some sort of internal IP address range:
1 10.1.10.1 1530.273 ms 0.307 ms 0.242 ms
2 * * *
3 10.210.19.242 140.028 ms 139.751 ms 139.963 ms
4 10.210.11.74 139.713 ms 140.141 ms 150.210 ms
[...]
Any ideas how to successfully establish a tunnel using aiccu? According to the verbose output log, the tunnel is established, but nothing gets through afterwards.
Thanks & best regards,
Thorsten

AICCU is a tool. That tool implements some support code for three protocols: TIC, heartbeat and AYIYA.
What you need is AYIYA support and the hope that the ISP does not block the AYIYA port.
As long as the AYIYA packets reach the PoP unharmed (only IP addresses in the header NATted and nothing else mangled) and those packets can also come back to you, everything should work as a charm, even if there is a triple NAT in effect.

Hi,
that's what i assumed - and therefore bad news for me right now... I have no idea what's the issue here. I'm not able to successfully establish a dynamic IPv6 tunnel via O2 3G or Vodafone 3G. Anybody else having problems, connecting via O2 or Vodafone? I didn't tried T-Mobile 3G yet, but will probably do tomorrow.
Help/ideas to get this tunnel running is highly appreciated :-)
cheers & best regards,
Thorsten

switched to AYIYA since it was not enabled before - now it's running fine.
thanks & best regards,
Thorsten
