VPN Firewall and Network Management

This chapter describes how to use the network management features of your ProSafe VPN
Firewall 200 FVX538.
This chapter includes the following sections:
• "Performance Management" on this page
• "Configuring Users, Administrative Settings, and Remote Management" on page 6-8
• "Monitoring System Performance" on page 6-23

Performance Management

Performance management consists of controlling the traffic through the 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 VPN firewall has the necessary features and tools to help the network manager
accomplish these goals.

Bandwidth Capacity

The maximum bandwidth capacity of the VPN firewall in each direction is as follows:
• LAN side: 1,800 Mbps (eight LAN ports at 100 Mbps each, plus one Gigabit LAN port)
• WAN side: 200 Mbps (load balancing mode, two WAN ports at 100 Mbps each) or 100 Mbps
(rollover mode, one active 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 WAN ports will support the following traffic
rates:
• Load balancing mode: 3 Mbps (two WAN ports at 1.5 Mbps each)
• Rollover mode: 1.5 Mbps (one active WAN port at 1.5 Mbps)
As a result and depending on the traffic being carried, the WAN side of the VPN firewall will be
the limiting factor to throughput for most installations.
