I've been unable to get AICCU AYIYA to work from behind a 2wire HomePortal (DSL gateway). aiccu starts as expected, and thinks all is well. However, looking at tcpdumps, it's pretty clear that the UDP packets are either not making it out past the gateway, or the responses are not making it back in past the gateway. Locally, all the IPv6 pings work great. But IPv6 pings to the POP side are never responded to; no other IPv6 traffic flows either. I've sent an email to 2wire's support org asking them, but am not hopeful. The same AYIYA tunnel works from behind a Linux NAT box at a different location, so I'm sure that aspect is working fine. Does anyone have any configuration suggestions on the 2wire gateway that would alleviate this? Thanks, Matt
