If the Preserve Pre-NAT feature is enabled, dataplane crashes may occur, which could result in firewall reboots.

Workaround: Disable the Preserve Pre-NAT feature using the set deviceconfig setting preserve-prenat-feature no CLI command.

Bootstrapping the VM-Series firewall on OpenStack with user-data does not function correctly. When you run the command show system bootstrap status shows, the output shows the message No Install media detected.

(PA-3400 Series firewalls only) The firewall might unexpectedly reboot and enter maintenance mode due to a ctd-agent out-of-memory (OOM) condition when undergoing advanced services load testing with a high volume of IoT EAL log forwarding.

Workaround: Limit the number of EAL logs generated by the firewall using the following CLI command: debug iot eal key-value EAL_PENDING_BYTES=1000.

When exporting and importing the CSV file, the hash values of pre-shared key (PSK) variables set at template and template stack levels inconsistently change, resulting in both variables displaying the same hash value.

When applying filters or searching for logs in the PanoramaMonitorLogssection, you might experience slow performance.

An SSL/TLS Client Hello may not be transmitted out of the firewall if the Client Hello arrives in multiple TCP segments and the traffic is not subject to SSL decryption (for example, SMTP over SSL).

Early aging and removal of firewall session while they are still active can lead to intermittent instabilities and crashes for proxy traffic, the Content and Threat detection engine, and any data-path processing.

When Panorama is not internet-connected and you try to upload images to the managed firewalls by using the Validate option, the upload fails with the following error: Failed to create multi-upload job. No valid software deploy targets found.

(PA-1400 Series firewalls, PA-3400 Series firewalls, and PA-5400 Series firewalls only) When the pan_task process restarts, control plane packets are dropped, which can impact LACP and pings to host interfaces.

Firewalls in HA configurations were experiencing consistent memory leaks on the active firewall, leading unexpected failovers while using Cloud Identity Engine (CIE).

The command show auth radius-require-msg-authentic might return no output.

When the DHCP server is enabled for GlobalProtect, the commit error message is not properly displayed when Any is selected as the source interface in the service router configuration ( DeviceSetupServiceService Router Configuration).

When the GlobalProtect DHCP feature is enabled with two primary DHCP servers on the GlobalProtect gateway, the gpsvc gets stuck during renewal and after HA failover.

TLSv1.3 hybridized Kyber support in the latest versions of Chrome and Edge browsers results in dropped Client Hello packets when SSL/TLS handshake inspection is enabled.

Workaround: Disable SSL/TLS handshake inspection.

If you change the service route of gp-ip-mgmt in Device > Setup > Services > Service Features > gp-ip-mgmt and Commit, the change won’t take effect. gp-ip-mgmt continues to use the last committed service route.

Workaround: After you change the service route interface for gp-ip-mgmt, navigate to either a GlobalProtect portal or gateway, click OK to save the configuration, and Commit the changes. This commit will include the service route change.

Panorama and the firewall display inconsistent IP addresses for device group members after manually syncing.

The Advanced DNS Security trial license and trial license information cannot be activated and viewed, respectively, on a managed firewall (with expired or active status) from Panorama. These tasks can only be performed on the firewall.

When Advanced Routing is enabled, IP multicast is not supported. An upcoming version will provide support for this feature. Customers who have multicast configured or who plan to deploy multicast routing should not upgrade to 11.2.0. Additionally, when Advanced Routing is enabled, the BGP dampening configuration isn't applied to any peers or peer group; the configuration is preserved but has no effect on BGP. Customers can use BGP even if they have applied a Dampening profile to a specific set of peers. The issue doesn't affect any other BGP features.

The VMX hardware version was upgraded from vmx-10 to vmx-15 on ESXi and NSX-T. Support for vmx-15 is supported on ESXi 6.7 U2 and onwards. Palo Alto Networks recommends that you upgrade your ESXi version if it is less than 6.7 U2. For more information, see the compatibility matrix.

When the firewall is running PAN-OS 11.2.0 and Advanced Routing is enabled, DHCPv4 relay agent functions successfully, but DHCPv6 relay agent doesn't work.

If you change the configuration of a firewall acting as a PPPoEv4 or PPPoEv6 client, old routes from the Forwarding Information Base (FIB) and route table for an inherited configuration with dynamic-identifier or client remain visible. Old routes also remain visible for an inherited interface when you execute the CLI command, show interface all.

Workaround: Unconfigure and configure the Inherited Interface.

The X-Forwarded-For (XFF) value is not displayed in traffic logs.
