Abstract: Technologies directed to network address translation based on logical channels in a shared private network with a single ingress to an ISP and multiple customer devices are described. One method receives a first public IP address assigned to an endpoint device by an ISP. The method creates a sub-interface on a WAN interface and adds a first rule that translates the first public IP address to a first private IP address assigned to the customer STA and a second rule that translates the first private IP address to the second public IP address. The first customer STA creates a second sub-interface between the customer STA and the endpoint device, adds a third rule that translates the first private IP address to a second private IP address assigned to the first endpoint device, and adds a fourth rule that translates the second private IP address to the first private IP address.

Abstract: Network hardware devices organized in a wireless mesh network (WMN). A first mesh network device performs a three-stage discovery protocol; in a first stage, a discovery scan uses a first radio to find a set of neighbor devices in proximity; in a second stage, a discovery locate probe process is performed on a secondary discovery channel that is from a same frequency band group as a first DFS channel; in a third stage, a CAC is performed via the first DFS channel and, after the CAC, a neighbor peering request is sent and a neighbor peering response is received from a second mesh network device via a second radio. The neighbor peering response confirms establishment of a first communication channel between the second radio of the first mesh network device and a radio of the second mesh network device over the first DFS channel.
