The VPN device is a hardware/software security system that
processes data packets as they pass between the public side and
the private side of a network.
The device can be added to your network as the primary firewall,
work in conjunction with an existing firewall, function as a
bridge, work in conjunction with routers, and in conjunction
with more than one VPN device can be used for load balancing
and redundancy for VPN Client connections.
The VPN device performs three major functions:
•
At the communications level, the VPN device can act either
as an IP router or as an IP bridge; that is, it operates at layer
3, not layer 2.
•
As a packet encryptor, the VPN device can selectively
encrypt and decrypt data based on source and destination
addresses and ports. This provides the flexibility of sending
both encrypted and clear data using the same infrastructure,
without compromising your centrally managed security
policy.
•
As a firewall, the VPN device can be used as a packet filter
and a stateful inspection proxy. The VPN device goes further
than traditional firewalls, however, by adding authentication
to the creation of tunnels, which allows the creation of truly
secure virtual private networks for VPN tunnels that
terminate outside the firewall.
