Hi.
This is a known limitation of WinPcap with NdisWan adapters. It is
documented in the release notes (but not in the winpcap docs, sorry):
Version 3.1 beta, 3 feb 04
a.. Support for capture on NdisWan, with the following features:
a.. Based on the NetMon API, does NOT use NPF.sys
b.. Works with PPP (dial-up) and VPN links
c.. Works on Windows 2000 and XP, only
d.. Packet transmission is not supported
e.. Packet filtering is done at user level
Have a nice day
