Chapter 6
VPN Firewall and Network Management
This chapter describes how to use the network management features of your ProSafe Gigabit 8
Port VPN Firewall FVS318G.
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: 8000 Mbps (eight LAN ports at 1000 Mbps each)
• WAN side: 1000 Mbps (one WAN port at 1000 Mbps)
In practice, the WAN side bandwidth capacity will be much lower when DSL or cable modems are
used to connect to the Internet. 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.
