Hello, After days of trying i gonna ask of someone here knows the sollution. I wanna setup a ipv6 tunnel. I resisted on go6.net and setup the hole thing. Everything is working if Eset personal firewall is off, but when it is enabled it wont connect anymore. Looking in Eset shows me thayt icmp6 is blocking. Is there anyone who has a ipv6 tunnel whit Eset 4 and knows what the problem is? Strange thing is that the Teredo tunnel also not working whit the Eset firewall on. Turning it off and it work. So is Eset blocking ipv6? Using: Vista sp2 x64. thanks for the help.
