PacketForward is an IP packet capture and forward application based on libpcap and libnet. It is a command line tool that listens on one network interface for UDP and TCP packets and then injects them on the same or another network interface. It has options for packet capture filtering and changing destination address.
Note: This application runs within the Terminal.app and does not have a graphical user interface.
Version 0.8.1: Changed the makefile for easy configuration. Corrected minor errors in the readme file related to getting libnet.
Mac OS X 10.4.8 or later, Intel-based Mac, Terminal.app.
