There's the problem (from my PoV) - my ISP (Andrews and Arnold) seem to 
be expecting me to use a tunnel without global scope ipv6 addresses on 
it.  That is, they provide the IPv4 address of their end of the tunnel 
but that's it.

Most configuration instructions assume the provider will give you an 
IPv4 address (for the remote end) and then a pair of IPv6 addresses for 
the actual link.  The bit I quoted above is from a page of instructions 
claiming to tell you how to configure a link without such a pair, but 
they don't seem to work.

I think I'll have to contact A&A on Monday and ask them how they expect 
it to work.

Thanks for your help
John
