RE: Tunnel IPv6 requests to my IPv4 servers?

In a word, 6tunnel. It's an application level proxy that does the job
well enough to get you out of trouble. Another approach would be to run
netcat (nc) from inetd on the port in question.

That said, I'll add my voice to the suggestion that it is very simple to
get IPv6 going on pretty much anything (OK, probably a pain on windows
2000 but even there it is theoretically possible). Rather than doing
NAT, you simply apply policy with your firewall rules where it should
always have been.

Subject: Tunnel IPv6 requests to my IPv4 servers?


I got my first IPv6 from ARIN. I set up my router and am successfully
advertising my IPv6 block. On my DNS server, I added an IPv6 IP, no
problem (try pinging! ns1.monkeybrains.net). Now, I'd like to 'NAT' to

some older boxes and not mess with actually putting IPv6 IPs on those
boxes. Say I had a box with running IPv4 with: 69.147.83.40
How would I 'nat' or 'gif' or 'tunnel' from a NAT box without putting
any IPv6 on 69.147.83.40?

I want to have:
2607:f598:0:1::666 on my 'firewall' and have it tunnel to 69.147.83.40

or whatever....
I've read this:
http://www.freebsd.org/doc/en_US.ISO8859-1/books/handbook/network-ipv6.h
tml
But that seems more geared toward getting IPv6 on clients.
