Vista - Multiple Tunnel Adapters in Vista

Hi,

I'm running Vista Ultimate and noticed recently that I have many "Tunnel
adapter Local Area Connection* nn" (nn=different numbers for different
connections). Most show the Media State as "Media diconnected", but a couple
are different, e.g.

Teredo Tunneling Pseudo-Interface
Microsoft ISATAP Adapter #5

with different IPv6 addresses.

Can anybody shed some light on this and is there any intrusion risk
associated with them?

Thanks

Microsoft ISATAP, Teredo Tunneling Pseudo-Interface are used for IPv6 and needed by the operating system, the other adapters are used internally by Vista`s kernel for network support.

They do not pose a secuity risk if your machine is running the latest windows updates, I myself have 10 device adapters (istap, RAS async, teredo tunnel and 5 different WAN miniport devices) If they show up in your network & sharing center then it would be a concern.

Thank you very much, dmex. None of these connections show up in my Network &
Sharing Center, and I tend to keep my computers up-to-date, especially wrt
critical and important Windows updates and AV/Firewall updates.
