How to modify and resend packet in network

Question

I'm doing an exercise ARP sniffing.

I want to simulate a attack like Man in The Middle. I had been sending arp to change way packet to Attacker PC. But I don't know How to forwarding this packet I receive from A to B.

How I do it? Can I do it with LibIPQ, or Libnet.

Recomend to read this post:

and need view this proyect SharpPcap.

and not forget read: Can you use ARP-Poisoning (spoofing) to apply simulated external effects?
