Summary

Teredo (RFC 4380) is an IPv6 transition technology that provides IPv6 connectivity across the IPv4 Internet for hosts that are located behind an IPv4 network address translation (NAT) device and are assigned a private IPv4 address.

Configuration

Discovery of Teredo Server happens only if the machine is discovered as a DirectAccess server. The following registry key is checked: HKLM\SYSTEM\CurrentControlSet\Services\iphlpsvc\DirectAccess\TeredoRelayEnabled, value=1. This registry key is not always created by default when the DirectAccess server is configured, so you should verify that it is enabled.
