[exim-dev] IPv6 reachability of tahini

I've been having ongoing problems reaching tahini over IPv6 from a SixXS
tunnel. Anyone else notice similar problems?

I'm suspecting ACLs somewhere in Cambridge's network.

I have no problems with IPv6 from my colo-box, so can ssh without
issues. The problem is accessing the web-services from my laptop at
home. If I use Firefox and disable IPv6 support, there are no issues.

The problematic source IP is:
2001:4830:113b:0:5ab0:35ff:fe60:52b6

Anyone?
