[Winpcap-users] winpcap on localhost interface??

[Loris Degioanni]

As far as I know, there's no way to capture loopback traffic at the MAC 
level in windows.
Or, better, there's no way to capture TCP/IP traffic, because tcpip.sys 
manages loopback internally, and just doesn't spit out any packet that 
NIC drivers (like the MS loopback driver) or other protocol drivers 
(like WinPcap) could see.

I think you have other ways to see loopback traffic (e.g, using the 
Packet Filtering API, Filter-Hook Drivers or similar solutions present 
in Windows), but none of them give you MAC-level access like WinPcap.
