# $OpenBSD: Makefile,v 1.1 2012/07/10 12:43:54 bluhm Exp $
# The following ports must be installed:
#
# python-2.7 interpreted object-oriented programming language
# py-libdnet python interface to libdnet
# scapy powerful interactive packet manipulation in python
# This test needs a manual setup of four machines
# The setup is the same as for regress/sys/net/pf_fragment
# Set up machines: SRC PF RT DST
# SRC is the machine where this makefile is running.
# PF is running OpenBSD forwarding through pf, it is the test target.
# RT is a router forwarding packets, maximum MTU is 1300.
# DST is reflecting the ping and UDP and TCP echo packets.
# RDR does not exist, PF redirects the traffic to DST.
# AF does not exist, PF translates address family and sends to DST.
