Why does GlobalProtect IP not change to the pre-logon's IP pool when user logs off?

• GlobalProtect (GP) App
• Supported GP App version
• Pre-logon connect method
• Preserve-tunnel-upon-user-logoff-timeout is set to 0

1. This is an expected behavior where the user tunnel is renamed to pre-logon when the user logs off.
2. "preserve-tunnel-upon-user-logoff-timeout" setting is not for pre-logon connect method.

• "preserve-tunnel-upon-user-logoff-timeout" set to 0 terminates the tunnel only for user-logon and on-demand connect methods.
• Security policy enforcement can be applied to "pre-logon" users by adding this username under Source User tab of the policy.
• If GUI is not available to see the users, following CLI command can be executed to see connected users.
