SendPacketToAdapter – sends packets outgoing (ie. to the NIC)
SendPacketToMstcp – sends packets incomming (ie. to the windows TCP stack)

[peterpiper]

I use:

const

ETHERNET_HDR: integer = sizeof(Char)*14;

IP_HDR: integer = (sizeof(Char)*20);

TCP_HDR: integer = (sizeof(Char)*20);



...



pIPHeader := Pointer(integer(pEtherHeader)+ ETHERNET_HDR);

Thank-you for your reply. I have winPKfilter capturing packets (displaying MAC addresses etc.). I dont see any way to get the headers/protocol of the packets for inspection, i assume you put the packets in to some data structure.

Is there any other help or code examples because looking throught the forum I see refrences to code like:

pIPHeader: TIPHeaderPtr;

pTCPHeader: TTCPHeaderPtr;

Which i dont see in the help file. Do you get additional help when you purchase the product? (i am using demo at the moment – umm time to reset the computer again 🙂

Cheers Pete.

Is it possible to use both packet level and application level filtering with in the same program ie. inspect packet using winPKfilter then a LSP/TDI filter?

Does your company provide a application level filter?

Thanks for your swift reply. Pete.
