Game : Steam Elite Dangerous : Ports and Prefixes

Here is a list of all ports and prefixes for use with Steam and Elite Dangerous. These can be imported into a firewall and are known to "just work. At least to me. For use with OPNSense / PFSense syntax.

OPNSense makes handling that many prefixes a littel easier
The many prefixes can be automated by copying them into a flat text file.

OPNSense documentation documents both URL tables for importing many hosts and list nesting to use one list constructed from multiple smaller lists which makes writing rules more manageable and modular.

• OPNSense URL Tables to import many IP at once
• OPNSense nested lists (for Hosts only)
