The ping was just simple test I was using to confirm connectivity. I didn't do a traceroute because after trying a few destinations, I was pretty sure the issue was with the tunnel. > > When I had no > > success I tried pointing a browser to a v6 destination - google > > obviously didn't work, then took swisscom's front page which didn't > > work either. > > Which just heavily indicates that your connectivity is broken, one way > or another (might just be a firewall). > > > I realized that maybe the tunnel was to blame.

I'm pretty confident my issue was timing issue. The pppoe session took long to come up and the sixxs interface was trying to start before ppp0 was up and thus couldn't bind to the local endpoint. Thank you for your help but afaic the issue is sorted out for me. I check for the local endpoint's ipv6 address at the end of the boot sequence. If it's not there I restart the sixxs interface and then it works.
