Skorpion Router
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.
