Overview

vArmour's OpenStack integration contains two components:

• L3 Agent replacement: This component configures vArmour firewall to be the gateway of internal networks and supports SNAT and Floating IP (DNAT) functions. It inherits neutron L3 Agent module. Instead of using iptables, the module makes RESTful API calls to program vArmour firewall.
• FWaaS driver: Based on neutron FWaaS service extension, this component is a FWaaS driver implementation that configures vArmour Firewall.

Firewall as a Service vArmour driver

Configuration

Please refer to FWaaS Installation Guide on how to enable FWaaS service

• Add the following configuration to l3_agent.ini to specify vArmour firewall director's IP address and login account

/etc/neutron/l3_agent.ini

[vArmour]
director = 127.0.0.1
director_port = 443
username = varmour
password = varmour

• Modify fwaas_driver.ini to use vArmour's FWaaS driver

/etc/neutron/fwaas_driver.ini

[fwaas]
enabled = True
driver = neutron.services.firewall.drivers.varmour.varmour_fwaas.vArmourFwaasDriver

• Modify neutron-l3-agent script to start vArmour's L3 Agent

/usr/local/bin/neutron-l3-agent

#from neutron.agent.l3_agent import main
from neutron.services.firewall.agents.varmour.varmour_router import main

• Restart L3 Agent

python /usr/local/bin/neutron-l3-agent --config-file /etc/neutron/neutron.conf --config-file=/etc/neutron/l3_agent.ini --config-file /etc/neutron/fwaas_driver.ini
