Configure a Palo Alto Networks (PAN) Firewall with Firmware 8.0 and Up

The purpose of this article is to provide a sample configuration. At the time of article creation, this device was in a known working state on the firmware used. 

Keep in mind different firmware versions will interact with hosted VoIP services in different ways. While this device may be fully functional on the tested and/or current firmware version, it is possible newer revisions will cause disruptions in service or make a device fully compliant with the required settings for hosted VoIP services where it was previously not.

 

For Palo Alto Firewalls on firmware 8.0 and above. For configuring a Palo Alto Networks Firewall with firmware lower than 8.0, refer here.

Objective

Configuring a Palo Alto Networks Firewall for 8x8 services.

Note: Guidance on Palo Alto Networks firewalls is publicly available within Palo Alto Networks device documentation.

Applies To

  • Palo Alto Networks firewalls

Procedure

Administrative Information

  1. Make sure your firewall is powered on and connected to your network.
  2. Connect the RJ-45 Ethernet cable from the RJ-45 port on your computer to the MGT port on the firewall.
  3. If necessary, change the IP address on your computer to an address in the 192.168.1.0/24 range (e.g., 192.168.1.3).
  4. In a browser on a computer on the same network as the Palo Alto Networks firewall, navigate to https://192.168.1.1
  5. Log in (default credentials shown below).
    • Username: admin
    • Password: admin
Note: If you are not able to connect to the web interface, consult the quick start guide for your particular device model for additional options.
Adding/editing 8x8 subnets is recommended when available. Please click here and review the X-series documentation as well as the ZTP documentation.

Additional Information 

The phones require a minimum UDP and TCP time out of 300 seconds or 5 minutes, depending on the network setup these settings may need to be modified on the PAN

Known Issues

  • Specifically Fax services don't work reliably with the higher resolution codecs
  • 8x8 Video Meetings has various issues, investigation is ongoing to find the best configuration for meetings
  • 8x8 currently recommends not using firmware 9.x.x. This may change as future updates are rolled out by Palo Alto Networks

Additional configuration

If needed, the 8x8 XML file can be uploaded to your Palo Alto Firewall. Follow the steps below if you would like to import the XML file to the PAN firewall.

  1. Right-click this link and save the 8x8 App XML for PAN Firewalls to your computer.
  2. Go to Objects > Applications.
  3. Click Import.
