Objective

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

Applies To

• Palo Alto Networks Firewalls

Procedure

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 lower than 8.0. For configuring a Palo Alto Networks Firewall with firmware 8.0 and higher, see Configure a Palo Alto Networks (PAN) Firewall with Firmware 8.0 and Up.

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. 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://192.168.1.4
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 or editing 8x8 subnets is recommended when available. Review X Series Technical Requirements.

5. On the Destination tab, set the Destination Address by adding the Destination Address group you created earlier.
6. Untrust the zone for your network.
   
   
7. On the Protocol/Application tab, select UDP.
8. Copy and paste all of the following UDP ports into the Port field: 5060,5061,5196-5199,5299,5399,5301,5401,5443
