GlobalProtect Portal Interfaces Web Interface Initial Configuration VPNs GlobalProtect Hardware PAN-OS
Symptom
On configuring GlobalProtect and assigning a tunnel interface to the GlobalProtect VPN, we see a warning message popup in the Commit/Validate saying:

Warnings:
– Warning: tunnel tunnel.1 ipv6 is not enabled. IPv6 address will be ignored!
– (Module: rasmgr)
 


Environment
PAN-OS 
GlobalProtect
Interface configuration for VPN


Cause
The support for IPv6 GlobalProtect clients has been introduced in PAN-OS 8.0, and you are not using IPv6 for GlobalProtect.



 


Resolution
This warning can be eliminated by enabling the option "Enable IPv6 on the interface" under Network > Interfaces > Tunnel > tunnel.x and check the box "Enable IPv6 on the interface."
 


Additional Information
We can also fix the issue by disabling IPv6 firewall globally on the firewall under Device > Setup > Session > Uncheck Ipv6 firewalling
