PAN-57145

Fixed an issue where, if the firewall performed IP and port NAT in the path of a GlobalProtect Large Scale VPN (LSVPN) IPSec tunnel, a re-key caused the firewall side to temporarily change back to the default port number for the new tunnel, and the intermediate NAT device dropped traffic until the old tunnel timed out or was deleted manually. With this fix, when a re-key happens, the firewall searches and applies the correct port number to the new tunnel immediately, which prevents traffic drops.
