As topic, i would like to use the following.
Subdomain1.domain.com = proxied via Cloudflare.
Subdomain1.domain.com:7278 =not proxied but redirect to proper dns.
So skip proxy and bypass cloudflare if cusom
Port is used.
I need this setup because the application need the right certificate in the backend to be hosted when useing that port. And fronting the :80 an 443 proxied is just protecting the website by not showing the proper IP.
I have player with the setting and firewall rules.
