Note:
Reducing the RTS Threshold and the Fragmentation Threshold too much can
have a negative impact on
performance.
Note:
Setting an RTS Threshold value equal to the Fragmentation Threshold value
effectively disables RTS.
I am not getting the full speed. What should I do?
•
The actual speed is always less then the theoretical speed, and degrades with
distance.
•
Read the section about reception problems. Better reception means better speed.
•
Check that all your wireless stations support the wireless standard you are using
(802.11g or 802.11g Super), and that this standard is enabled in the station
software. Transmission speed is determined by the slowest station associated
with the access point. For a list of wireless stations that support 802.11g Super,
see www.super-ag.com.

Overview
The ZoneAlarm router allows you to connect the LAN and the WLAN network segments
at the data-link layer, by configuring a bridge between them. A bridge allows you to
choose whether to enable the firewall between the LAN and WLAN:
•
If you enable the firewall, the WLAN and LAN will be assigned separate,
isolated IP networks, and the gateway will operate as a regular firewall between
the LAN and WLAN, inspecting traffic and dropping or blocking unauthorized
or unsafe traffic according to the defined firewall policy.
•
If you disable the firewall between the LAN and WLAN, they will appear as a
single unified network; that is, the two network segments will share the same IP
address range, and traffic will flow freely between them. Only traffic from the
LAN and WLAN to the Internet will be inspected by the firewall.
The ZoneAlarm router allows you to configure anti-spoofing for the bridged network
segments. When anti-spoofing is configured for a segment, only IP addresses within a
specific IP address range can be sent from that network segment. For example, if you
configure anti-spoofing for the LAN network segment, the following things happens:

•
If a host with an IP address
outside of the allowed IP address range
tries to
connect from the LAN network segment, the connection will be blocked and
logged as “Spoofed IP”.
•
If a host with an IP address within the bridge IP address range tries to connect
from a network segment
other than the LAN segment
, the connection will be
blocked and logged as “Spoofed IP”.
Multiple Bridges and Spanning Tree Protocol
When using multiple bridges, you can enable fault tolerance and optimal packet routing, by
configuring Spanning Tree Protocol (STP - IEEE 802.1d). When STP is enabled, each
bridge communicates with its neighboring bridges or switches to discover how they are
interconnected. This information is then used to eliminate loops, while providing optimal
routing of packets. STP also uses this information to provide fault tolerance, by re-
computing the topology in the event that a bridge or a network link fails.
Note:
The ZoneAlarm router license allows configuring one bridge; however, STP
can be used in situations where multiple bridge devices exist on the same network.
Workflow
To use a bridge
1.
Add a bridge.
See
Adding and Editing Bridges
on page 141.
2.
Add the LAN and WLAN networks to the bridge.
See
Adding Internal Networks to Bridges
on page 145.
3.
If you enabled the firewall between networks on this bridge, add security rules
and VStream Antivirus rules as needed.
For information on adding security rules, see
Adding and Editing Rules
on page 176.
For information on adding VStream Antivirus rules, see
Adding and Editing Vstream
Antivirus Rules
on page 252.
