5-port Rugged Industrial Gigabit Firewall / Router

Industrial Gigabit Firewall / Router (GUARD-F2)


The GUARD-F2 adds to the MPL Networking product range an additional rugged Industrial Gigabit Firewall and VPN Router. The GUARD-F2 comes with 5 Gigabit Ethernet interfaces. The proven GUARD housing allows to operate the Firewall in harsh environments without the need of fans or ventilation holes and can easily be mounted on a 35mm DIN rail or wall. The compact housing offers sufficient space to add a MAGBES (Managed Gigabit Switch) or other peripherals. The GUARD-F2 can be tailor made to your needs, even with IP67 housing and MIL connectors or Open Frame with locking headers.

The GUARD-F2 Highlights

The operation temperature range is from -20°C to +60°C and optionally up to -40°C to +85°C without fan or case openings. The capability to offer copper as well as SFP ports for various fiber optical solutions makes the product universal. The internal miniPCIe slot allows various extensions (WLAN, GPRS...).

These features make the GUARD-F2 to the ideal and most secure solution for all rugged industrial and defense applications, where quality, reliability, low power consumption, and long-term availability are key. The GUARD-F2 can be used, e.g. for railway, maritime or defense applications and the OpenWRT gives you the security you need in your environment.

The GUARD-F2 is available for different Industries and is the perfect solution for industrial environments, railway applications, MIL/COTS applications, or whenever a rugged long-term available firewall/router is needed.

The GUARD-F2 comes preinstalled with an adapted version of OpenWrt (www.openwrt.org). 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.

Functions and protocols:
  • TCP/IP V4 and V6, IPsec
  • QoS (Quality Of Service) capable
  • SIIT(IPV4-over-IPV6 translation)
  • Miredo/Teredo (IPV6 over IPV4 tunneling)
  • PPP (Point-to-Point Protocol)
  • Network address translation
  • Multi WAN Setup (failover and load balancing)
  • DHCP Server for IPV4 and IPV6
  • DNS server/forwarder
  • Support for dynamic DNS providers
  • OpenVPN support
  • OpenConnect client support
  • Firewall based on Linux iptables
  • SSH and telnet device access
  • Snort (lightweight intrusion detection)
  • Routing daemons (OSPF, RIP, BGP, ...)
