The earliest recollection of this bug is traced back to PAN-OS 11.2.10-h2 - September 04, 2026. This bug is fixed in PAN-OS versions 11.2.10-h2, 12.1.5, 11.2.7-h8, 11.2.4-h14. Fixed an issue where, when SD-WAN Direct Internet Access was configured and traffic traversed the cellular interface without a NAT policy rule, intermittent cellular modem connectivity issues occurred, which caused the firewall to disconnect and reconnect to the cellular network. To use this fix, run the CLI command set session teardown-upon-fwd-zonechange yes .
