Router and Network Management

6-1

This chapter describes how to use the network management 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 status, perform diagnostics, and manage the firewall 
configuration file.

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.

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.
