ipv4 over ipv6

10/04/2009 - 09:05 von Florian Doersch | Report spam
Hi,

i recently set up ipv6 in my network, and now i tried to disable ipv4
- but: I cant open ipv4-sites from the ipv6-only machines.

What do I have to do?

I found anything about 4to6 (only about 6to4)

on my router, I use radvd with AdvOtherConfigFlag on, and dibbler-
server to provide dns-server-address.

My testclient is a vista-pc with disabled ipv4.

I can open ipv6-sites without any problem on that machine, but ipv4
does not work.

firefox says "waiting for " and after a while I get "connection
reset".

Some iptables/forwarding problem?
Did I forgot something?

Thank you for your help!

Of course not.

Leave IPv4 on as long as you need to talk to IPv4 hosts.

It's all a stinking pile of ugly brown steaming hacks, that do not
work properly. Don't use it when you have the slightest chance of
avoiding it.

However, you can find some listed in chapter 4 of:

Of course. How should they be able to communicate with a V6 hosts
unless they are dual-stack?

More of a fundamental problem. You found the incompativility between
IPv6 and IPv4.

Thank you for your help!
