OK I may be thick but in case there's anyone else out there similarly afflicted, I can tell you that the answer is right there in the most obvious place - on the WinPcap website!! See http://winpcap.polito.it/misc/dialup.htm Mike Thackray Nokia Networks e-mail [EMAIL PROTECTED] Hi, I need to be able to capture packets from applications running over GPRS on Windows 2000 machines. These use serial cable / infrared / Bluetooth connections to the mobile device but all use the Windows 2000 PPP driver NDISWAN and I can't capture from it. I know this is a problem with NDISWAN itself and not Ethereal / WinPcap, but does anyone out there know of a work around or alternative method, short of changing the operating system?
