Discussion

Teredo is an IPv6 transition mechanism that involves tunneling IPv6 packets encapsulated in IPv4 packets. Unauthorized tunneling may circumvent network security.

Check Content

Verify the "Miredo" service is not running:

# ps ax | grep miredo | grep -v grep

If the Miredo process is running, this is a finding. 

Note: For Appliance OS, "Miredo" is not included by default, this is not a finding.

Fix Text

Kill the "Miredo" service.

Edit startup scripts to prevent the service from running on startup.
