I disabled my ipv6 tunnel a few weeks ago, because I wasn't at home. Now its enabled again, but it doesnôt seem to work. I already uninstalled and re-installed the ipv6 protocol (under windows xp), but that doesn't solve it (it did in the past). A strange thing that i noticed was that the set or show firewall adapter doesn't work: C:\netsh firewall show adapter De volgende opdracht is niet gevonden: firewall show adapter. And the rule in my script to activate the tunnel has the same problem: C:\netsh firewall set adapter SixXS icmp all=enable De volgende opdracht is niet gevonden: firewall set adapter SixXS icmp all=enabl e. I don't know if this is the thing tha causes my problem, but a fact is that i can't ping any ipv6 address, and my computer can't be pinged too. So i get mails with tunneldowntime from sixxs. I hope someone can help me. I don't know how, but suddenly it worked again. Maybe i just need to be more patient.
