I know I have two routers, and I followed all the instructions in the guide. My router IP matches that of my modem, but it still won't let me start of my Minecraft server. I don't know if this is the problem, but it tries to run the server off of the 10.0.0.1 IP instead of the new one. My modem is extremely old, and I'm really not sure if I changed the settings properly. I'm assuming that the problem is with my new router, as I did not have this problem with my old Linksys. Attached are images from the modem settings, not the router's.
