Synopsis :

A Teredo server is listening on the remote host.

Description :

The remote host is running a Teredo server. Teredo is a protocol for
tunneling IPv6 over UDP, and is used to give nodes the ability to
obtain IPv6 connectivity behind IPv4 network address translation (NAT)
devices. A Teredo server is a node that is connected to both IPv4 and
IPv6 networks.
