Simple Module TCPSpoof

Package: inet.transportlayer.tcp_common
File: src/inet/transportlayer/tcp_common/TCPSpoof.ned

Sends fabricated TCP packets. This is a base implementation, you'll probably have to customize it in C++ according to what you want to send and when you want to send it.

Compatible with both IPv4 (IPv4) and IPv6.
