would you believe it, avast 2014 as started blocking ipv6 teredo now, working yesterday fine, ive uninstalled, wiped all avast entries, installed again, still blocks teredo ipv6 when firewall is on, also, when using secureline it completely disables teredo, never used to with previous version, I could still use it.Thisis really peeing me off, reinstalling/repairing and nothing comes it. Does anyone know what rules to add so teredo ipv6 will work without having to turn firewall off and on first. Don't understand why its just started blocking it though, the rules must of been there before.
