Varnish Cache for WordPress on cPanel

[LuDo8]

I'm trying to get Nginx working with Varnish. I have Varnish set on Port 80, and in Nginx.conf to port 8080. Saved and rebooted all services.

So my question is:

How do I know Varnish is Working? VS my website being just served up by Nginx. If I visit mydomain.com:80 the site loads, if I go to mydomain.com:8080 I got 403 Forbidden.

I also ran Varnishtop command and this is what I get:

list length 35
