See, the problem isn't really getting URL Snooper to work with a dialup modem. It's getting WinPCap to work with a dialup modem. WinPCap isn't a DonationCoder application, so we are probably not the best people to "get a dialup modem and work on it". That would probably be best handled by the WinPCap people.
Did you try the demo here to see if it works on your dialup?http://www.microolap...rk/tcpdump/download/
If it does, then mouser would like to know, because then he can do something to help you. He can add support for that network engine in URL Snooper.
So, try it and please let us know.
