Hi Rick and Diane and all, Although you can't use WinPcap v.3.x to capture on PPP interfaces, you may be able to capture successfully using WinPcap 2.3 (April 10 2003) and Windows network monitor, see <http://winpcap.polito.it/misc/dialup.htm> I use WinPcap running on Windows 2000 5.00 on an IBM Thinkpad T30. I am connecting to a GSM phone with a USB Bluetooth adapter manufactured by Level 1, using dial-up networking via GPRS. I have enabled the Windows network monitor and then capture on the NdisWanBh adaptor. It works just fine. Hope this helps, best regards, Mike
