The FAQ for the WinPcap library, which is what Ethereal uses to capture
packets on Windows, says that it doesn't support capturing from WAN
devices, such as PPP sessions on modems, on Windows NT.

The FAQ is at

	http://netgroup-serv.polito.it/winpcap/misc/faq.htm

and it says:

	Q-2: Can I use the packet driver on a PPP connection?

	A: We have tested the packet driver on PPP connections under
	Windows 95 and Windows 98 and it seems to work well.  Under
	Windows NT and Windows 2000 there are problems with the binding
	process, that prevents a protocol driver from working on the WAN
	adapter if it is not written by Microsoft.
