Hi,

I need detail documentation about PFIL_HOOK. It would be really nice if anyone can provide me any documentation regarding PFIL_HOOK. I have searched on the internet but I could not find any detail documentation of PFIL_HOOK. I found one paper " Hooking Filters for Fun and Profit: PFIL_HOOKS". But I found it insufficient to understand PFIL_HOOK.

I need to use PFIL_HOOK to capture ipsec packets after these packets are received and decrypted by the user.

Regards,

Irfan Ahmed
