Assigning an Interface with a DHCP IP Address as the Portal/Gateway GlobalProtect IP

• Interface is enabled with DHCP to receive the IP Address.
• This interface is used for GlobalProtect Portal/Gateway.
• When trying to select the IP address for portal/Gateway, it does not display the IP address used on the interface.

• Palo Alto Firewalls
• PAN-OS 9.0 and above
• GlobalProtect (GP) Portal
• GlobalProtect (GP) Gateway

• When the DHCP is renewed and a different IP address is assigned to the interface, the configuration of Portal/Gateway will become invalid.
• To prevent this, the GP Portal/Gateway displays the IP address as "None" when the DHCP interface is used.

1. This is expected behavior when an interface is set to DHCP.
2. The DHCP interface can be selected to be used by GlobalProtect Portal and/or Gateway, but the IP address remains as None. 
3. The dataplane will automatically use the dynamically assigned IP address of that interface when the user connects.
4. Below is a screenshot displaying the option of None in the dropdown selection for ethernet1/1 IP address as it uses DHCP.
