Performance Management

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

Bandwidth Capacity
The maximum bandwidth capacity of the wireless VPN firewall in each direction is as follows:
•
LAN side. 8000 Mbps (eight LAN ports at 1000 Mbps each).
•
WAN side. 1000
Mbps (one active WAN port at 1000
Mbps).
In practice, the WAN-side bandwidth capacity is much lower when DSL or cable modems are
used to connect to the Internet: The typical traffic rate is 1.5 Mbps. As a result, and
depending on the traffic that is being carried, the WAN side of the wireless VPN firewall is the
limiting factor for the data rate for most installations.

Features That Reduce Traffic
You can adjust the following features of the wireless VPN firewall in such a way that the traffic
load on the WAN side decreases:
load on the WAN side decreases:
•
LAN WAN outbound rules (also referred to as service blocking)
•
DMZ WAN outbound rules (also referred to as service blocking)
•
Content filtering
•
Source MAC filtering

You can control specific outbound traffic (from LAN to WAN and from the DMZ to WAN). The
LAN WAN Rules screen and the DMZ WAN Rules screen list all existing rules for outbound
traffic. Any outbound rule that you create restricts outgoing traffic and therefore decreases
the traffic load on the WAN side.

On the LAN WAN screen, if you have not defined any rules, only the default rule is listed. The
default LAN WAN outbound rule allows all outgoing traffic.
