The FVS338 ProSafe VPN Firewall 50 offers many tools for managing the network traffic to
optimize its performance. You can also control administrator access, be alerted to important events
requiring prompt action, monitor the firewall status, perform diagnostics, and manage the firewall
configuration file.

Performance Management
Performance management consists of controlling the traffic through the FVS338 VPN firewall so
that the necessary traffic gets through when there is a bottleneck and either reducing unnecessary
traffic or rescheduling some traffic to low-peak times to prevent bottlenecks from occurring in the
first place. The FVS338 VPN firewall has the necessary features and tools to help the network
manager accomplish these goals.

Bandwidth Capacity
The maximum bandwidth capacity of the FVS338 VPN firewall in each direction is as follows:
•
LAN side: 800 Mbps (eight LAN ports at 100 Mbps each)
•
WAN side: 100 Mbps (rollover mode, active broadband WAN port at 100 Mbps)
In practice, the WAN side bandwidth capacity will be much lower when DSL or cable modems are
used to connect to the Internet. At 1.5 Mbps, the broadband WAN port will support a traffic rate of
1.5 Mbps (active broadband WAN port at 1.5 Mbps). After a rollover, the serial dial-up WAN port
bandwidth will be much lower.

bandwidth will be much lower.
As a result and depending on the traffic being carried, the WAN side of the firewall will be the
limiting factor to throughput for most installations.
