Tcpreplay is a suite of BSD licensed tools written by Aaron Turner for *NIX operating systems which gives you the ability to use previously captured traffic in libpcap format to test a variety of network devices. It allows you to classify traffic as client or server, rewrite Layer 2, 3 and 4 headers and finally replay the traffic back onto the network and through other devices such as switches, routers, firewalls, NIDS and IPS's. Tcpreplay supports both single and dual NIC modes for testing both sniffing and inline devices.
To install tcpreplay, run the following command in macOS terminal (Applications->Utilities->Terminal)
sudo port install tcpreplay
