Colin,

|
| Something very simple in perl would be:
|
| #!/usr/bin/perl
| print "Content-type: text/plain\n\n";
| print ($ENV{REMOTE_ADDR} =~ /[A-Fa-f0-9]{4}:/ ? 'Remote host supports
| IPv6' : 'Remote host supports IPv4');
|
| and including it in your ssi:
|
| <!--#include virtual="/perlscript.pl"-->
|
| Good luck.
|

Thanks Colin, I have entered the script and included it in the footer of 
every page.
However, I still suspect I have a problem elsewhere now. The page always 
says
to me that I support IPv4 and does not recognise my v6 connection. I can 
access
every other v6 preferred site no problems and they all say I am connecting 
via IPv6.

Is this something I can not test 'Internal' to the network or is my incoming 
connection
to the web site not working via IPv6. netstat -an tells me IPv6 is Listening 
on [::]:80.

I think I may need to sort out exactly which interface I am supposed to 
listen on, and also
which connection the Freenet6 tunnel is supposed to connect to.

Can someone look at those last two points for me after looking at my 'ipv6 
if' output.
(ipconfig does not show the 3ffe address given to me by Freenet6 at all)

in tcpc.conf I have put

if_tunnel = 4
if_prefix = 2

I am sure I have a wrong config somewhere.

Thanks

Gav...
