IP routers link two Internet Protocol (IPv4) networks together – passing appropriate traffic while blocking all other traffic. One of the networks is designated the local-area-network (LAN) and the other the wide-area-network (WAN). IP routers are used to isolate traffic and for gaining access to remote equipment. Contemporary Controls’ wired routers provide Ethernet-to-Ethernet routing and will accommodate external Ethernet-based modems. The wireless routers provide access to the Internet via the cellular network.
