Coming to think of it... if you have installed the tunnel to accept incoming IPv6 from your ADSL line, and so the interface for the ADLS line has an IPv6 address, I do not see how you can stop applications from making outgoing IPv6 connections via that interface, unless you explicitly configure the application to not do so.
So unless you tell binkp not to make outhoing IPv6 call, it will use the tunnel and the ADSL line for outgoing IPv6.
I suspect the same goes for your browser. What does ipv6-test.com say?
