Hi im new in VMWare ESXi and i want to know how to block port 80 because this show a default welcome web in my Host... for security purposes i want it blocked.
I think, you have to remove the page or create a custom firewall rule on ESXi:

How to Create Custom Firewall Rules in ESXi 5.0 | virtuallyGhetto
I already made it activating the Firewall and blocking services via command-line, i notice the Firewall is not enabled by default when you install ESXi.
You do not have option to modify firewall rules during installation of esxi. It has very minimal options during install to customize ( if you are using iso based default installation, scripted install has better option to customize things) . But after installation you can make modification to all configuration and they persist across reboots
