I have a Toughswitch 5 configured for three DtD nodes, 1 lan, and one WAN. Port 1 has a nanostation M2 XM as a WAN Gateway, Port 2 is LAN for port 1 with a Raspberry PI running Asterisk attached. Port 3 has a Nanobridge M5 attached, Port 4 is an AR with two webservers, VOiP phone, AP, and a couple Raspberry Pis attached. This node is configured for 13 DHCP addresses. Port 5 is my WAN port.
