This policy setting allows you to configure the Teredo refresh rate. Note: On a periodic basis (by default, every 30 seconds), Teredo clients send a single Router Solicitation packet to the Teredo server. The Teredo server sends a Router Advertisement Packet in response. This periodic packet refreshes the IP address and UDP port mapping in the translation table of the Teredo client's NAT device. If you enable this policy setting, you can specify the refresh rate. If you choose a refresh rate longer than the port mapping in the Teredo client's NAT device, Teredo might stop working or connectivity might be intermittent. If you disable or do not configure this policy setting, the refresh rate is configured using the local settings on the computer. The default refresh rate is 30 seconds.
