When you specify a security level, the corresponding security settings are automatically
configured, but other settings, such as address type, local address, and remote address must still be
configured manually.
After you specify a security level, you can still make changes to the auto configured settings. When
you change an auto configured setting, the security level switches automatically to "User Setting".
