Hi folks, could you give me a hint about my XP setup. It changes it's IPv6 address on ervery reboot and I see several temporary IP's on it. I'm using a ayiay tunnel on my linux router and have attached a subnet for my local network. All is running fine but on my local xp workstation I see this above mentioned strange behavior.
