Testing the P4/C Firewall:

1.  Follow instructions on http://iconicsp4.cloudapp.net/ to install the NFP SDK RTE, 
	setup access to the ICONICS repository and identifying your SmartNIC
	
	  To install the package:
        yum install nfp-sdk6-p4-config-<smartnic>-p4c_firewall_state_table-<version>.noarch

      All the available packages can be listed with:
        repoquery -a --repoid=iconics

2.  The Firewall controller and test script will be installed to:
      /opt/nfp_pif/etc/smartnic-configs/<smartnic>-p4c_firewall_state_table/

3.    Run the Firewall Controller on the host where the SmartNIC is installed:
      python fw_v2_ctrlr.py -h
      python fw_v2_ctrlr.py -i 111.111.111.111 -t 100

4.  Run the Test Script where you generate your traffic:
      ./p4c-firewall-test.sh <internal port> <external port>
      ./p4c-firewall-test.sh p6p1 p6p2

      Make sure you have downloaded the .pcap files provided in this repo
      Make sure you have tcpreplay installed on your host:
        yum install tcpreplay
      The .pcap files must be in the same directory as the test script.

5.  Setup:
   ______________           ______________
  |   SmartNIC   |         |TraditionalNIC|
  |            p0|---------|p6p1<Internal>|
  |   Firewall   |         |              |
  |            p4|---------|p6p2<External>|
  |______________|         |______________|

  The test script will do the following:
    - Send a packet from <external> to p4: No rule yet -> Drop
    - Send a packet from <internal> to p0: New Flow -> NAT -> Forward to p4
    - Send a packet from <external> to p4: Known Flow -> NAT -> Forward to p0
