On my PC I have created PPPoE connection by RasPPPoE. At this time, I run listadapters sample and NDISWANIP adapter is active. But when I run passthrough sample, I can not find any packet flow from/to my PC nic. In order to verify issue further, open wireshark and see normal packet traffic with PPPoE header. From WinpkFilter specification, following text can be found:
Supported connection types:
WinpkFilter supports Dial-Up connections (Analog modem, ISDN modem), Ethernet (LAN and WLAN) connections, Cable/DSL modem using DHCP or “PPP over Ethernet” (EnterNet, RasPPPoE, WinPoET).
So what is root cause of this issue? Maybe something wrong with sample source code.
