Good Morning!

Pfsense 2.1 (latest iso x86)

Ipv6/Ipv4 both works now. I always monitor it to www.test-ipv6.com and the reply is 10/10 and after 40 minutes or so i get 1/10.. I have to reset state table and reboot the machine in order to get 10/10 again. But after few minutes i get 1/10 again..Any idea? Or is it because of this error?
