What Is The Teredo Tunneling Pseudo-Interface [SOLVED]

What Is It?

According to a Super User authority, the Teredo Tunneling Pseudo-Interface is a protocol that enables computer systems behind a NAT firewall (most consumer computer systems are) and with no native IPv6 connection to obtain remote IPv6 resources only using UDP protocol.

The concept is that home end users can begin accessing IPv6 web services before their local connection supports this protocol, making the changeover from IPv4 less difficult.

This was in response to a Windows 7 Ultimate user who discovered it after doing a ipconfig /all in the command prompt.

According to Wikipedia, Teredo is defined as a type of transition technology that provides full IPv6 connectivity for IPv6-capable hosts that are on the IPv4 Internet but don’t have a native connection to an IPv6 network.

It’s able to function even from behind network address translation (NAT) devices such as home routers, unlike similar protocols,

Another Super User poster explained, in a nutshell, it means you’ve got IPv6 installed within your networking components.

To check if you do:

  1. Head to Control Panel and double-click Network Connections.
  2. Then right-click the icon for your Local Area Connection and choose Properties in the menu.
  3. On the General page of the properties sheet, you will find there’s box that ought to contain an entry for Microsoft TCP/IP version 6.

The bottom line is that a majority of individuals have no need at the moment for IPv6. Having said that, it’s not going to result in issues if you keep it installed on your personal computer.

Removing IPv6, the user says, won’t make you lose your internet connection. The entry you see for Internet Protocol (TCP/IP) is the critical one.

Disabling It On Windows 7

A Super User posted a method for disabling it on Windows 7:

  1. Verify that you are an administrator
  2. Right click on Computer, select “Manage.”
  3. In the left-hand menu, beneath System Tools, left-click on “Device Manager.”
  4. Then, right-click on “Device Manager.”
  5. Hover over “View >” and click on “Show Hidden Devices” within the menu that appears.
  6. Within the center pane, locate a group called “Network Adapters” and pop it up it by double-clicking on it.
  7. You’ll see a listing of all of your adapters- you can disable it from here

The user says that he hasn’t experienced any issues after disabling these yet. If he becomes worried about being able to access resources on an IPv6 network, he’ll re-enable these.

Norton Perspective

A Norton AntiVirus user said that after leaving his computer running a Norton360 full system scan the next day his Security History showed multiple alerts:

IP address has disappeared from adapter Teredo Tunneling Pseudo-Interface“.

The message was followed up with “Protecting your connection to a newly detected network on adapter ‘Teredo Tunneling Pseudo-Interface’“. He was wondering what it meant.

A Norton user explained that through the changeover period from IPv4 to IPv6, a short-term method called Teredo tunneling is now being employed to “repackage” data packets and allow connection between IPv4 and IPv6 devices.

For example, employing the 6to4 protocol for tunneling IPv6 information to a system with an IPv4 address. Therefore, the “Pseudo-Interface” in the user’s security history messages.

The Teredo Tunneling Pseudo-Interface Code 10 Error

Over at Driver Easy, they report that some computer users are getting a yellow exclamation mark within Device Manager located beside the device “Teredo Tunneling Pseudo-Interface” and that its status is listed as “The device cannot start (Code 10).“.

This means that your system isn’t properly recognizing the driver.

Driver Easy lists 3 potential fixes that include Uninstalling all Teredo Tunneling Adapters & Interfaces, updating device drivers, and a fix using Command Prompt.

As we’ve seen, Teredo tunneling is a process for ‘tunneling’ IPV6 traffic over an IPV4 network.

Over in the Sharky Forums, a user says that there’s a range of problems with it, so he advises to make your network 100% IPV6 or 100% IPV4.


That said, the majority of regular home users are stuck with IPV4 because that is all their routers and switches are able to deal with.
