What is the Policy keyword "Application NONE"?

What is the Policy keyword "Application NONE"?

Setting the Application to NONE in a policy indicates that if an ALG (Application Layer Gateway) exists for a session that matches this policy, the ALG will be applied. This is the default behavior for all policies.

If you need to disable the ALG, then specify Application Ignore.  For more information, refer to KB13509 - Viewing list of ALGs and disabling an ALG differs on ScreenOS versions.

If you need to configure a custom service and want one of the firewall ALGs to be applied, then specify Application <service>.  Refer to KB7096 - Configure FTP with Custom Control Port (Other than 20) as an example.
