1. How can I use WinpkFilter for capturing packets from multiple adapters ?
You can start the dedicated thread for each network interface to capture and process packets from it, just like PassThru sample does. Another way is setting up events for each interface and using WaitForMultipleObjects.
2. Dose my WinpkFilter Appication NOT conflict with any other NDIS hooking drivers or WinpkFilter Applications ?
We can’t guarantee the compatibility with any other hooking drivers, but WinpkFilter is compatible with the majority of firewalls on the market. In order to avoid conflicts with other WinpkFilter applications you would need the custom build (with customized names for drivers and devices) of WinpkFilter drivers (free for the Developer license).
