Industrial Firewall and Router with Gigabit Switch

Industrial Firewall and Router with Gigabit Switch (µGUARD)


The µGUARD is a Firewall / Router / Access Point with long-term availability. The design is optimized for low power consumption, small size (SwaP) and highest flexibility, plus the capability for extended temperature. The µGUARD can be expanded with additional 10 ports over the µMAGBES (managed 10-port switch). The µGUARD and µMAGBES adds additional reliable and unique products to MPL’s Industrial Network Solutions.
The proven GUARD solution allows to operate the Firewall / Accesspoint in harsh environments like public transportation systems, rough industrial areas, or in defense applications.

µGUARD Highlights

The standard operation temperature range is -20°C to +60°C and optionally available in extended temperature The internal two miniPCIe slots and the M.2 slot allow various extensions (WLAN, GPRS. LTE mSATA SSD...). The µGUARD is available as OpenFrame on a cooling plate to be mounted in existing housings or cabinets. Alternatively we have firewall solutions with RJ45, M12, or MIL-38999 connectors. Fiber can be provided over the TX2FX.

These features make the µGUARD to the ideal and most secure solution for all rugged industrial, public transportation, and defense applications, where quality, reliability, low power consumption, and long-term availability are key. The flexibility of the well known OpenWRT OS gives you the security you need in your environment.

Standard Compliance
The µGUARD Family is designed to meet or exceed the most common standards. Particular references are:
EMC EN 55022, EN 55024, EN 61000, MIL-STD-461E
Shock & Vibration EN 60068
Environmental & Safety EN 50155, MIL-STD-810G, EN 60601, IEC / EN 62368
Approval List CE, IEC 60945, IACS E10

The µGUARD comes preinstalled with an adapted version of OpenWRT ( This Linux based embedded distribution provides all functionality required for operation as IPV4 and/or IPV6 firewall and router. The vast amount of additional packages available in conjunction with MPL support allows you to create a solution for every routing or firewall project.
Most of the configuration of the firmware installed can be done using a web based interface. For more specialized requirements, a console based configuration utility is available. All configuration is stored on the device in a human friendly text format and can be modified using a text editor, too.

Functions and protocols:
  • TCP/IP V4 and V6, IPsec
  • DNS server/forwarder
  • QoS (Quality Of Service) capable
  • Support for dynamic DNS providers
  • SIIT(IPV4-over-IPV6 translation)
  • OpenVPN support
  • Miredo/Teredo (IPV6 over IPV4 tunneling)
  • OpenConnect client support
  • PPP (Point-to-Point Protocol)
  • Firewall based on Linux iptables
  • Network address translation
  • SSH and telnet device access
  • Multi WAN Setup (failover and load balancing)
  • Snort (lightweight intrusion detection)
  • DHCP Server for IPV4 and IPV6
  • Routing daemons (OSPF, RIP, BGP, ...)
Further functionality can be installed using a package repository that contains more then 2000 precompiled applications ready to install. A software development kit (SDK), allowing to implement customer specific applications, is available as well.
