The DMZ port can be used to connect a third network, for example, one that manages a mail server. This server will be accessible from both the secure LAN and the unsecured WAN, but access to the LAN from the WAN is blocked because a firewall at each access point monitors and regulates incoming and outgoing data traffic. Furthermore, the DMZ port allows for remote maintenance of the machine or installation. Integrated switches can handle internal switching for small machines or installations, or they can be connected to larger networks.
Increasing cost pressures in the industrial sector are driving manufacturers of industrial routers to increasingly focus on all-in-one product strategies to minimize space requirements, power consumption, and installation costs. The new FL MGuard security routers combine routing, VPN, firewall, DMZ, and switching functions into a single device, thus meeting these new needs.
