Hello All,
I am changing the destination IP address of outgoing packets and source IP
address of incoming packets.
I am able to do this at NDIS IM driver level in Microsft Windows 2k (SP4),
but it is not working using Filter Hook driver on IPFltrDrv in Microsoft
Windows XP prof (SP2).
I am calcuting the chksum of TCP and IP after modification of packets in
both methods.
When calculating thru Filter Hook Driver 3 way handshake of TCP is possible
but after that connection breaks.
Please tell me is there any restrictions using FilterHook driver?
Thanks & Regards
