MultiCom Ethernet III

The Lightning MultiCom Ethernet III has a third Ethernet interface for a DMZ (Demilitarized Zone) or any other applications. Such applications include backup of an ADSL line using an ISDN router, like the Lightning Pocket MultiCom. The LAN interface has also an integrated four port full-duplex Ethernet switch. An IPSec option for 20 tunnels is available.

4 LAN Ethernet 10/100 switched ports interface + 1 WAN Ethernet 10 interface + 1 DMZ 10/100 interface.


Corporate-class unlimited firewall gateway for broadband Internet access.

MultiCom Ethernet III brings the security of large enterprise firewalls, combined with broadband Internet gateway functions, into an easy to install, secure and affordable solution for small and medium businesses. Three distinct Ethernet ports allow for dividing the network into a partially publicly accessible zone (such as E-mail, web or E-commerce server connected to the DMZ) and a completely protected zone (Intranet) to secure your sensitive company data.

The integrated firewall is based on the latest Linux kernel 2.4 and provides extensive protection. Stateful Packet Filtering keeps track of the individual data packets as well as open connections. High-performance Logging functionality provides protection from hacker attacks and warns the administrator of possible intrusions. Each data packet can generate different Syslog messages with varying security levels and text content. Combined with integrated functionality for Traffic Shaping, it is possible to log just the first packet of a potential attack, thus increasing the efficiency of reporting. Also new are extended features for Transparent Redirection, e.g. to a proxy server or for Load Balancing.

Main features include:

  • Security: built-in stateful firewall prevents attacks from intruders
  • High-speed: WAN 10 Mbit/s Ethernet port for broadband Internet access
  • VPN IPSec option
  • PPPoE, PPTP, DHCP, static IP, RIP I&II broadband access support built-in
  • Dynamic DNS services support
  • Easy connection: integrated 4-port Ethernet switching hub 10/100 Mbits/s
  • Time-saving: Easy configuration, remote management and remote firmware upgrade
