Multiple Tunnel Adapters in Vista


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?

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.
