Asus RT-AC66U remote access

192.168.x.x , 10.x.x.x, 172.16.x.x or private not routed to internet.
asus router with the 192.168.1.1 NAT
xfinity is using a router with 10.13.13.1 NAT
where is the wifi connected?
do all your nodes have the same network address eg:192.168.1.x
I see a double NAT, but that’s only a problem for incoming connections or if the nodes are connected in different NAT’s
