iLO 4 Remote Access

[reddoorsupplies]

Hi I am new to iLO and just looking to set it up on my new Proliant ML350G8 server.

I can use it internally fine and have activated the license.

What I want to do is setup access from off site. Now I can see the list of ports that I would need to point to it but I currently use 80 and 443 to go to an exchange server.

Do I just need to select different ports, say 81 and 444 from the web console and then that will allow me remote access or have I missed something?

Also do I need to install HP Insight Remote Support Hosting Device or is this something completely different?

Thanks for any help
