On a recent project using winpcap capture TCP packets, and calculate the flow on the development machine xp, single card, everything is normal, moved to the formal machine, Windows 2008 R2, double nic binding into a virtual network card, winpcap can correct to list all the network card:
But no matter choose which card, under the condition of the set filter conditions, cannot capture to TCP packets, remove the filter conditions, can be cut into some package, should be IP or other types, but I need to intercept the TCP packet, don't know the reason why is because the system or double nic binding problem, two card also must be bound into a network card, ask ace to give some inspiration
