Hi,

I'm wondering if I can inject packets into an already established tcp
connection.

at a specific moment,
I should be able to hold out-going packet and inject custom created
packet.
then I should be able to increment sequence numbers for all the
packets that i have hold and all subsequent outgoing packets.(or
something similar)

I'm thinking of using libnet to inject packets.
but I'm not sure about how to make sure tcp sequence numbers are
intact.

I'd prefer window platform for development.

Thanks in advance.

You need NDIS IM driver for that
