Firewall port requirements

Hi

I want to set up an AstroBox Pi for my Ultimaker 2+, is there any documentation on network requirements, I can’t find any. I’m behind a very restrictive firewall and I need to know what ports are required for example so I can allow it to connect to Astroprint.com.

Many thanks

We simply use port 443 (SSL) same as any https connection. While the port if a standard port (https) we do establish a WebSocket connection over it. Some proxies need special handling for this.
