The DFI attacks are legitimate. They are blocked and they should be blocked. Sleep well at night, Admin Tools has got you covered.
Regarding the tmpl issues, please do the following in the Components, Admin Tools, Web Application Firewall, Configure WAF page, towards the middle of the page:
- Block tmpl=foo system template switch => YES
- List of allowed tmpl= keywords => component,system,raw,unsupported
- Block template=foo site template switch => YES
- Allow site templates => YES
I marked the things you will need to change in red. These settings are what you need to provide the best protection for your site without blocking people who shouldn't be blocked.
PS: Thank you for the very thorough screenshots! They made it much easier helping you.
