Cascaded Networks are networks which are reachable through the local LAN interface but which have a different subnet from that used by the VPN Gateway local LAN interface. These networks are reachable through a router attached to the VPN Gateway local LAN interface. Cascaded Networks are configured through the AT&T Administration Server. By default, devices on cascaded networks will have access to the VPN tunnel. If this is not required, the Internet Only option in the Device Profile in the AT&T Administration Server should be enabled for the Cascaded Network.

Cascaded Networks not marked as Internet Only and attached to a VLAN will adhere to the routing rules of the VLAN. Refer to the section on VLANS for more information.
