Before starting any new setting, ALWAYS backup the current good setting first.Go to Files and click Backup option:
You may also want to copy the backup file to your computer should the router crash and you need to restore the last good setting.Select the backup file, click the Copy button:
Go to your computer folder, click Paste and the file will be copied:

You may need to continue revise & enhance the rules according to your needs.Once confirmed, again, ALWAYS make another backup and copy it to your computer!
