    I wanted to port forward my Plex server, but it said that I might have double-NAT. So I read that using the command tracert in cmd, I should be able to see if I have double-NAT.
    And the first two IPs were:
    192.168.2.1 and 192.168.1.254.
    My default gateway is 192.168.2.1, but it was once 192.168.1.1.

    So the 192.168.1.254 was really weird, because the default gateway is different.

    I then typed in the IP into my browser, and it wanted me to type a username and password, like when I go to 192.168.2.1. But all the passwords and usernames (including admin, admin) I tried is all wrong.

    I really don't which device it might be. So I thought that some one here might be able to help me find the device?

    Hi LaustDengsoe, and welcome to TSG.

    Please tell us the brands and exact model numbers of the routers, switches, and any modem you are using for your Internet connection and exactly how they are interconnected.

    If you are connecting your computer to a router that is then connected to a modem supplied by by your Internet Service Provider, you could very well be using double-NAT. Many modems include a router and would need to be configured as a gateway to bypass the NAT used by the internal router.
