Unfortunately, we *can't* confirm it.
That's because we can *deny* it:

"Q-6: Can I use WinPcap on a PPP connection?
A: We have tested WinPcap on PPP connections under Windows 95, Windows
98 and Windows ME. In Windows 95, due to a bug in NDIS, WinPcap
sometimes resets the PPP connection. In Windows 98/ME this bug appears
to be corrected, and WinPcap seems to receive correctly, however it is
not able to send packets. Under Windows NT/2000/XP there are problems

with the binding process, that prevent a protocol driver from working
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
properly on the WAN adapter. The problem is caused by the PPP driver of
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
WinNTx, ndiswan, that doesn't provide a standard interface to capture."
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
WinPcap 3.0 simply refuses to support the NDISWAN interfaces at all - it
doesn't even try:
http://winpcap.polito.it/misc/changelog.htm
"NdisWan support:
o due to the large number of messages reporting problems (blue
screens) with VPNs, PPTP and such connections, we have disabled the
support for NdisWan adapters. As a consequence, it is not possible
to capture from PPP (neither NdisWanIp, nor NdisWanBh, nor
NdisWanBfIn/Out...). At the moment we have no plans to fix the
problem with VPNs, PPTP, PPP unless we get a generous sponsorship."
