    For the longest time I've been trying to setup Ethernet and WiFi at the same time, WiFi for the server hosting and Ethernet for regular use but when I have the Ethernet connected I stop being able to connect to my server which is specifically listening on 192.168.2.9:25565 and That IP is in a DMZ On the router.

    When I disconnect the Ethernet however I can connect via WAN again.

    I'm on fedora 25 and have had this problem on Ubuntu, Debian and many other distributions.

    In case it's not clear when I disconnect the Ethernet cable from my laptop, On my Desktop which is on my Ethernet network I can connect VIA Wan.

    More information about the network setup is needed. What's the IP configuration for both the wireless and Ethernet interfaces?

    Note: When I check "Use this connection only resources on its network" I'm able to connect to the server again, But then I can't use my Ethernet for anything but internal use.

    I'm guessing you have a default gateway configured for both network interfaces. If so, that's your problem.
