Thanks for your comment.
Apologies for my slightly rude remarks about your document.
I shall read it again with more diligence.

But I have more or less decided to put IPv6 on the long finger.
I'm actually running Centos-5.2 on my server, with shorewall,
and it seems that shorewall6 is unlikely to be supported 
until Centos-6 comes out.

I don't want to run iptables directly, as I am not confident
that I would get it right;
and I don't know of any alternative to shorewall
which is available under Centos and which supports IPv6.

OK, I'll try putting that in.
At present radvd fails, with the error message:
helen radvd[4958]: IPv6 forwarding seems to be disabled, exiting
