Network
Open the gateway → the Network tab in my.cubepath.com.
It lists the gateway's public IPv4 and IPv6 addresses (with netmask and rDNS), the attached private network with its CIDR and the gateway's private IP, and the auto-generated outbound route (0.0.0.0/0 via the gateway's private IP) that sends private-network traffic out through the gateway; from here you can jump to the network's full route list.
