I'm a pretty novice person considering installing opnsense for my personal home use.

Their documentation has what would seem to be incomplete hardware requirement.

For example it does not list any network hardware. I assume you need at least 1 Ethernet connection. I recall reading somewhere that you might need 2 network cards? One for in and one for out?

What about network card specs? I have old computers lying around that exceed the CPU/RAM/SSD requirements but cards are practically antiques. Should I upgrade? If so, to what?

ETA: The best internet I could subscribe to where I'm at is 1024 Mbps down, 50 Mbps up. So don't worry about wasting fibre speeds. :(

Does anyone know about a more thorough description of requirements?

I've done crazy things and never had an issue with double nat. But that's all on small networks.

Assignment as in what opnsense is aware of.
Whether that is a physical NIC (NICs aren't assigned by default), virtual NICs (IE multiple vlans on a physical nic), or PPPoE/PPPoA/whatever

Watch a video of the install process, then watch a video of assigning additional interfaces.
They will be able to explain and show it to you better than I can type!
