Problem with Comodo Firewall

[tangooricha]

After updating Comodo firewall, my tunnel broker could not work. I have tried to config my computer on Windows XP following the instruction. But when I ping ipv6.google.com which IP is 2404:6800:8003::63, all of the result are Request timed out . I sniffed the traffic with wireshark when I was pinging. It seems that my host sended the ping requests and recieved the responds correctly. So maybe Comodo firewall blocked all of the traffic with protocol type 41, but I have ever add a correct rule with any source and dest inbound and outbound, why it still does not work?
