[Feature Request] List the ports that needs to be opened on Firewall

[aidin36]

I set up the server on an AWS EC2 instance. (Was very smooth! Thanks for the great script!)

By default, all inbound ports are blocked. I need to allow them through security policies. But I'm not experienced in networking, and couldn't figure out which ports I should allow for each protocol. The only one I know is MtProxy because it asked me what port I wanted during setup.

It would be great to include an option that shows which ports (on what protocols) need to be allowed. For example, after the start or restart of a service, the script can print a message like don't forget to allow port 8000/tcp in your firewall!.

I personally allow all protocols from everywhere in SG, but they should be placed in a separate VPC compared to others.
