Ubuntu as ipv6 router, not working

[snarked]

RE - Reply #14:  Diconnecting after 10 minutes seems like an application timeout issue.  Check your IRC settings and those of your server or peer.  It could be firewall related, but not strictly IPv6 transit related.  When it reconnects via IPv4, does that connection last or also time out?  If IPv4 connections last, then it's probably not the application.

Problem is windows. In linux i have no problems with reconnection in ipv4. I found out this today on my second computer.

Is any solution for this???

Is your windows machine changing it's IPv6 address?

I've noticed that the windows 7 machines on my network like to randomly change their addresses from time to time. They just seem to randomly generate the lower portion rather than using a unique sequence generated from the MAC.

That's on purpose...for privacy reasons.

You can change that behavior, but I doubt it's causing your problems.

@annoyingrob try with this
and please google this acctions first, you must know what are you doing

netsh interface ipv6 set privacy state=disable

netsh interface ipv6 set global randomizeidentifiers=disable
