First of all the bad news, its not possible to connect your Asus directly to the coaxial socket.
--> In oder to use your Asus as the router, you have to activate the Bridge-Mode on the Sunrise Connect Box.
To do that you have to switch your connection to IPv4:
Switch modem from IPv6 DS lite to IPv4 - Sunrise community
After that you should be able to activate the bridge mode in the connect box.
If this worked you can now connect your asus to LAN 1 of the Connect Box ant the Asus will
obtain a public IPv4 and acts as a fully router without double NAT.
