  What scenerio would require multiple Ethernet ports? Is two or even one sufficient for what I want to do?

    Adding to thejevans’ answer, if you were running a network analysis tool like Snort, it would be easier if you had multiple ports.

      I’ll keep that one in mind. Thank you

    Are you confusing “ports” with “interfaces”? I can see that happening since we do colloquially refer to both as ports depending on context.

    Each service will bind to it’s own “port” which is tied up by that service. However each interface (the external physical connection) supports like 65,000 software ports.

    Do in practice, no, you don’t usually need more than one physical network connection.

      I didn’t know that you could have two “interfaces” vs “ports”. I was talking about the physical ports knowing this. This helps me understand what @fiivemacs means. I’m definitely not going to be using more than one provider. Thank you!

    Backup internet

    Two (or more) seperate networks that need access to the same server. This is done so is network A is down, network B can still access the server.

      I didn’t know you could have to ISPs connected to one device. I won’t be requiring that however. I was wondering if besides the one port to connect my server to the router there was anything else I was missing or is commonly used that I should be aware of to take up another port.

        Well they would be going to the router and the router would be handling it, but you could still have seperate feeds from the router on lan/opt ports to the device.dont think they will both function at the same time though, system needs priorities

    I have two ports bonded on my server to get more speed, but I could get by with a single port just fine.
    If you need to connect to multiple networks you can use VLANs and a single ethernet port if you want to.
