6to4 relay implementation question

[Viktor Horváth]

Hello to everyone,

I need help to my Diploma thesis. I have to test 6to4 relay implementations
on openbsd. Which working 6to4 relay implementations are there out for
openbsd? (Including the tunnel maker softwares.)
Thank you for the answer!

greeting:
Viktor Horváth

Sixxs has a aiccu package, tunnel broker provides instructions for using the gif interface.  Wide-dhcp v6 works great with Comcast's native v6.

Besides the methods which were already mentioned, there's also gre(4),
and you can carry ipv6 inside ipv4 (and vice-versa) with ipsec (gif
is basically a version of this last case without the ipsec).

And other generic tunnelling protocols can be used, e.g. carrying v6 in
ethernet packets over a layer 2 tunnel, ssh tun forwarding, openvpn,
openconnect etc.

nat64 normally works in combination with a special dns resolver
(e.g. 'dns64' options in newer versions of BIND, there is a patchset
for unbound to do this, totd) and as the name implies works by address
(and protocol) rewriting rather than tunnelling.
