I am using the Spitz AX (GL-X3000) as a modem/gateway (WIFI disabled), I have an Asus Router as the main router where all the clients connect, the Asus Router is connected to the Spitz AX (GL-X3000) via an Ethernet cable, the Asus router is already doing NAT with IP V4, is there a way to disable the NAT on the Spitz AX (GL-X3000) to avoid double NAT?
Usually double nat can be solved by disabling upnp. Upnp runs on these routers from stock but you need the doodah in luci to turn it off… By doodah I mean the luciupnp.app plugin…
Would it help if you put your Asus in the DMZ of the Spitz AX?
