McAfee Next Generation Firewall (NGFW) and Brocade vRouter/ODL Controller - Secure Programmable Virtual data Center Threat Management:

Version 2



    Intel Security and Brocade have collaborated to create a joint solution that provides data center an advanced threat protection while off-loading unnecessary Next Generation Firewall Layer 7 analysis.


    Solution Overview


    One of the main features of this design is the ability to self-defend the network. When a hacker sends malicious traffic, McAfee Next Generation Firewall (NGFW) will identify and block that malicious traffic flow and informs McAfee Security Management Center (SMC). The McAfee Security Management Center (SMC) communicates with the Brocade Vyatta Controller (SDN/ODL) which dynamically reprograms Vyatta vRouter. The controller inserts rules into Vyatta vRouter to block malicious traffic from the hacker and allow benign traffic flow to pass.

    As shown in Figure 2, Brocade SDN Controller inserts rules into Vyatta vRouter to block malicious traffic and allow benign traffic to pass.

    Solution Benefits


    The benefit of the self-defending network is the ability to reduce Layer 7 analysis once the malicious flow has been identified and blocked by Next Generation Firewall. This allows the Next Generation Firewall to retain its resources that can be used for Layer 7 analysis of other traffic flows. Such a self-defending secured network provides agility, flexibility and high reliability for mission critical network services.

    OpenStack Installation


    This section covers installation of Redhat version of Openstack known as packstack and OpenDayLight on a 2 Node setup. The document assumes that the user has knowledge of openstack components and Horizon UI.


    System Requirements

      • Node 1 for OpenStack control, compute and network. To be referred as control node
      • Node 2 for OpenStack compute. To be referred as compute node.

    Note: You can use either physical machine or VM's for the setup.

      • Option 1 (Node 1&2): OpenStack directly on Physical Server 2 Servers each with 2 NIC interface Ex: Supermicro Micro server 64 GB RAM, 1 CPU 8 core processor, 1TB HDD

      • Option 2 (Node 1&2): OpenStack on a ESXi VM 2 VM's each with 3 NIC interface Ex: VM  (24 GB RAM, 4 VCPU 4 core processor, 300 GB HDD)


    System Preparation


    On both Computer and Control Node

      1. Install CentOS 7 x64
        • Server with GUI
        • Ensure hostname is set
        • Create standard partition for the installation (ex. /boot – 20GB, / - 900 GB, swap – 30GB)

    Note: By default mount point '/' space is used by Open stack for its VM's hence try allocate maximum space to it.


      2.  Typically interface are named as enoxxxxxxx, which is not easy to use. To change to legacy naming ethx execute the below steps:

        • Edit file /etc/default/grub
        • Edit line containing GRUB_CMDLINE_LINUX  add net.ifnames=0 to the string
        • Save the file
        • Execute "grub2-mkconfig -o /boot/grub2/grub.cfg"
        • Execute "reboot"
        • After reboot move ifcfg-enoxxxxxxx to ifcfg-ethx under /etc/sysconfig/network-scripts/.


      3.  Copy scripts folder and sample packstack file “packstack-answers-os-floatingipsupport.txt” that is inside scripts folder to "/root "

        • Ensure system has internet access, before running the scripts below
        • Execute the script "" that installs all the dependencies and Openstack packstack
        • Manually edit the network scripts to assign the management IP address
          • Update /etc/sysconfig/network-scripts/ifcfg-br-ex (External/Floating IP)
          • Update /etc/sysconfig/network-scripts/ifcfg-eth0 as below:








          • Update key values in /etc/sysconfig/network-scripts/ifcfg-eth1 and add the management ip address.

    Here are the keys to be updated:

    Update key values in /etc/sysconfig/network-scripts/ifcfg-eth1 and add the management ip address. Here are the keys to be updated





          • Execute service network restart
        • Manually edit /etc/hosts file, to include the hostname of control and compute node, localhost ip
          • ex: osodlphy1 osodlphy2 osodlphy1.sddc

    On Control node

      4.  Execute "packstack --answer-file=packstack-answers-os-floatingipsupport.txt"


    Setup floating IP for external network access


      1. Get a range of unassigned IP address which will be used as floating IP for VM's inside openstack tenant

      2. Create a public network with name public and then execute below command

      3. $ neutron subnet-create --name public_subnet --enable_dhcp=False --allocation-pool=start=<start ip>,end=<end ip> --gateway=<gateway> public <subnet cidr>

      4. Ex: neutron subnet-create --name public_subnet --enable_dhcp=False --allocation-pool=start=,end= --gateway= public


    Verification of the setup


    Test OS - ODL setup with Floating IP support with the following steps.


      1. Execute commands in "" manually in the command line, running all commands together in the script may not succeed
      2. 2 VM's should be in running state and able to ping each other, this ensures openstack installation is successful
      3. Allocate and associate a floating IP to the VM
      4. Verify the VM is ping-able from the floating ip network, and access internet
