Skorpion IP (EIPR) industrial-grade router/switch has such a stateful firewall, port forwarding, network address translation (NAT), port address translation (PAT) and dynamic host configuration protocol (DHCP) on both the LAN and WAN sides. The switch’s built-in firewall provides security by allowing an industrial network to communicate through the IT network to the Internet, while blocking unwanted communications from the IT network.
