1Introduction
The FL MGUARD protects IP data connections by combining the following functions:
– Network card (FL MGUARD PCI4000)
– VPN router (VPN - Virtual Private Network) for secure data transmission via public
networks (hardware-based DES, 3DES, and AES encryption, IPsec protocol).
– Configurable firewall for protection against unauthorized access. The dynamic packet
filter inspects data packets using the source and destination address and blocks
undesired data traffic.
The device can be configured easily using a web browser.
Network features – Stealth (auto, static, multi), router (static, DHCP client), PPPoE (for DSL), PPTP (for
DSL), and modem
–VLAN
– DHCP server/relay on the internal and external network interfaces
– DNS cache on the internal network interface
– Administration via HTTPS and SSH
– Optional conversion of DSCP/TOS values (Quality of Service)
– Quality of Service (QoS)
–LLDP
– MAU management
–SNMP
Firewall features – Stateful packet inspection
–Anti-spoofing
– IP filter
– L2 filter (only in stealth mode)
– NAT with FTP, IRC, and PPTP support (only in router modes)
–1:1NAT(onlyinrouter network mode)
– Port forwarding (not in stealth network mode)
– Individual firewall rules for different users (user firewall)
– Individual rule sets as action (target) of firewall rules (apart from user firewall or VPN
firewall)
Anti-virus features – CIFS integrity check of network drives for changes to specific file types (e.g.,
executable files)
– Anti-virus scan connector which supports central monitoring of network drives with
virus scanners

FL MGUARD
10 PHOENIX CONTACT 8334_en_02
VPN features – Protocol: IPsec (tunnel and transport mode)
– IPsec encryption in hardware with DES (56 bits), 3DES (168 bits), and AES (128, 192,
256 bits)
– Packet authentication: MD5, SHA-1
– Internet Key Exchange (IKE) with main and quick mode
– Authentication via:
– Pre-shared key (PSK)
– X.509v3 certificates with public key infrastructure (PKI) with certification authority
(CA), optional certificate revocation list (CRL), and the option of filtering by subject
or
– Partner certificate, e.g., self-signed certificates
– Detection of changing partner IP addresses via DynDNS
– NAT traversal (NAT-T)
– Dead Peer Detection (DPD): detection of IPsec connection aborts
– IPsec/L2TP server: connection of IPsec/L2TP clients
– IPsec firewall and 1:1 NAT
– Default route over VPN
– Data forwarding between VPNs (hub and spoke)
– Depending on the license: up to 250 VPN channels
– Hardware acceleration for encryption in the VPN
Additional features – Remote logging
– Router/firewall redundancy (can be installed later for each license, not for firmware
version 7.0))
– Administration using SNMP v1-v3 and FL MGUARD device manager (FL MGUARD
DM)
– PKI support for HTTPS/SSH remote access
– Can act as an NTP and DNS server via the LAN interface

Introduction

1.1 Device versions
The FL MGUARD is available in the following device versions, which largely have identical
functions. All devices can be used regardless of the processor technology and operating
system used by the connected computers.
FL MGUARD RS4000/ 
FL MGUARD RS2000
The FL MGUARD RS4000 is a security router with intelligent firewall and optional IPsec
VPN (10 to 250 tunnels). It has been designed for use in industry to accommodate strict
distributed security and high availability requirements.
The FL MGUARD RS2000 is a version with basic firewall and integrated IPsec VPN
(maximum of two tunnels). Its scope of functions is reduced to the essentials. It is suitable
for secure remote maintenance applications in industry and enables the quick startup of
robust field devices for industrial use, thereby facilitating error-free, independent operation.
Both versions support a replaceable configuration memory in the form of an SD card. (The
SD cards are not supplied as standard.) The fanless metal housing is mounted on a DIN rail.
The following connectivity options are available

FL MGUARD SMART2 The FL MGUARD SMART2 is the smallest device version. For example, it can be easily
inserted between the computer or local network (at the LAN port of the FL MGUARD) and
an available router (at the WAN port of the FL MGUARD), without having to make
configuration changes or perform driver installations on the existing system. It is designed
for instant use in the office or when traveling.
The FL MGUARD SMART2 is a further development of the FL MGUARD SMART.
Figure 1-2 FL MGUARD SMART2
FL MGUARD PCI4000 The FL MGUARD PCI4000 has the design of a PCI-compatible plug-in board.
The FL MGUARD PCI4000 is suitable for distributed protection of industrial and panel PCs,
individual machines, or industrial robots. It has a configuration memory in the form of a
replaceable SD card, which can be easily accessed on the front.
Figure 1-3 FL MGUARD PCI4000
FL MGUARD DELTA TX/TX The FL MGUARD DELTA TX/TX is ideal for use in desktop applications, in distribution
compartments, and other environments close to production process with low requirements
for industrial hardening.
Individual devices or network segments can be safely networked and comprehensively
protected. The FL MGUARD DELTA TX/TX can be used as a firewall between office and
production networks as well as a security router for small and medium-sized workgroups.
