it is actually depends from the particular implementation .
Would you say that:
WinpkFilter IM NDIS driver works with IPsec and IPv6
WinpkFilter hooking driver does not work with IPv6 and IPsec?
WinpkFilter driver can be installed below or above IPsec driver.
WinpkFilter IM NDIS driver is above the IPsec and
WinpkFilter hooking driver is below or vice versa?
