[SOLVED] Firewall Setup for Cloud hosting web app

[Bambos]

Hello everyone,

i'm working on a cloud hosting for a web app, that will be also server for android app.

There is a dns name with the form of "thewebapp.domain.com" that is already pointing on the public IP. The datacenter has pfsense ISO available, so is my choice to go.

What would be the suggested firewall port allow for something like this ?
Should this be normal port forward from WAN to LAN server IP? or there is a usage scenario of reverse proxy ? (HA Proxy?)

In this kind of cloud hosting, do we forward everything inside (as the developer requested) or only the specific services and ports ?
(Actually they request a VM with direct public IP without firewall in the front)

any comments / suggestions appreciated.

I would only expect to need to forward port 443 for a web app. But it may need other ports, they would need to tell you what's required.

You should really direct the developer to a network security primer as soon as possible.
This guy is a security menace!
