Palo Alto firewalls can be very simple to use and implement, or they can be very difficult. Because there are so many possible components and areas of configuration in these firewalls, understanding the basic features can be helpful. Management vs Data Plane Most network equipment is split into 2 (or more) basic components: a management […]
In this scenario we will be setting up a simple Microsoft Exchange mail server to be accessed by the internet. We will assume all Exchange services are on the same host, and all clients are on the internet. To begin, we start by looking at the available documentation. A brief internet search turns up https://docs.microsoft.com/en-us/exchange/plan-and-deploy/deployment-ref/network-ports?view=exchserver-2019 […]
In these standard access list activities we walk through how firewalls evaluate traffic and the 5 tuples used to permit or deny traffic. We then walk through an example activity using packet tracer. Second activity using Standard Access Lists. This walks through evaluating our firewall requirements, viewing the flow of data, and identifying the rules […]
In this video we walk through the initial power on and configuration of a Palo Alto firewall. We configure the management interface from the command line and then connect to the web interface. Inside the web interface, we review how to change the IP, gateway, and DNS settings. Palo Alto Command Line Interface (CLI) Default […]
An introduction to firewalls, what they are for, and how they work. We include an overview of the 5-Tuples used in firewalls and how they are evaluated by a network device. Finally, we walk through setting up a simplified firewall rule using Standard Access Lists.
