Introduction

• Gigabit performance
The FB600 series are provided in a number of variants. This manual is for the FB6402. This variant includes:
• Border Gateway Protocol, to allow routes to be announced and accepted from peering BGP routers.
• IPsec/IKEv2 implementation for providing secure tunnelling and roaming VPN capability.
1.1.2.1. FB6402 Gigabit stateful firewall
The FB6402 provides a larger scale firewall than the FB2500 and FB2700, handling millions of active sessions
with comprehensive IP and port mapping. The FB6402 makes an ideal head of rack unit for hosted servers
allowing multiple VLANs each with independant firewalling rules, DHCP assignments, traffic shaping and
VPN support.
1.1.3. Ethernet port capabilities
The FB6000 has two Ethernet network ports that operate at 1Gb/s. The ports implement auto-negotiation by
default, but operation can be fine-tuned to suit specific circumstances. The function of these ports is very
flexible, and defined by the device's configuration. The ports implement one or more interfaces.
Multiple interfaces can be implemented on a single physical port via support for IEEE 802.1Q VLANs, ideal
for using the FB6000 with VLAN-capable network switches. In this case, a single physical connection can be
made between a VLAN-capable switch and the FB6000, and with the switch configured appropriately, this
physical connection will carry traffic to/from multiple VLANs, and the FB6000 can do Layer 3 processing
(routing/firewalling etc.) between nodes on two or more VLANs.
1.1.4. Product variants in the FB6000 series

• FB6702 Tunnel endpoint / gateway
1.2. About this Manual
1.2.1. Version
Every major FB6000 software release is accompanied by a release-specific version of this manual. This manual
documents software version V1.46.100 - please refer to Section 4.3 to find out more about software releases,
and to see how to identify which software version your FB6000 is currently running.
If your FB6000 is running a different version of system software, then please consult the version of this manual
that documents that specific version, as there may be significant differences between the software versions.
Also bear in mind that if you are not reading the latest version of the manual (and using the latest software
release), references in this manual to external resources, such as the FireBrick website, may be out of date.
