Router and Network Management
This chapter describes how to use the network manag ement features of your ProSafe VPN
Firewall 200. These features can be found by clicking on the appropriate heading in the Main
Menu of the browser interface.
The ProSafe VPN Firewall 200 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 stat us, perform diagnostics, and manage the firewall
configuration file.
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 traf fic 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 firewall will be the
limiting factor to throughput for most installations.
