Teredo uses return routing to discover the closest Teredo relay corresponding to any given peer. Discovery is achieved by sending an
ICMPv6 Echo Request and waiting for the appropriate relay to forward the ICMPv6 Echo Reply back. Unanswered ICMPv6 Echo Requests make Teredo clients assume that the peer is unreachable. This document identifies two scenarios where a middlebox should
detect the lack of
ICMPv6 Echo Reply and craft one toward the Teredo client in order to avoid possibly erroneous peer unreachability assumptions.
