if you want to test please contract me from bbs message. 🙂
about the send rst packet,it is very important.
we known,the firewall’s important point is protect the host. if we deny the bad ip from the host,for the first time,we will see the host remain a port state:Time_wait.
if we deny many and many ip,the host we get over of the States.
Then like Time_wait, the windows system will keep it for 20 minuts at last.
i suggest add one api for winpkfilter. the api can send any Tcp flag packet. by pass in last tcp packet and tcp flag,we can get the buffer. at last,we can send this packet.
just a sample.
and eg: sendFlagTcppacketToadpatch……
by the way,how to get the IFS HOOK like winpktilter(NDIS HOOK)?
