Control Hypervisro ESXI 5.1 Over Internet

Hi,

I want to control my server over the internet. I tried to connect with vSphere client in the same network, and all works great.

Now I wanna try to connect to my server over the internet. I read in different sites that I have to open these ports ( 80, 443, 902, 903 ).

I try it, but the client not work. I have open the my ip address by browser and I have receive 403 Forbidden....

How I can connect to it?

Thanks to all !!

Giovanni
