ipv6 with Windows XP

April 15, 2009 at 15:04:12
Specs: Windows XP
I have just re-installed XP instead of Vista. and i cannot get ipv6 connectivity unless i put my PC in the DMZ of my router. netsh show teredo says that it is behind a symmetric NAT, which mean teredo will not work. However, i have the exact same router that i used when i had Vista installed and on Vista ipv6 connectivity perfectly straight out of the box. Just wondering if there is something funny about XP and the way it detects NAT behind a router / firewall. Any help would be greatly appreciated.

Note :: That ipv6 only works on mt windows XP if i have my computer in the DMZ of my router. Just incase that wasn't clear. thanks.

Doesn't sound like you have your router configured to support ipv6. My linksys has check boxes for both.
