Section ² - Configuration
Firewall Settings
This section will allow you to setup a DMZ host and to enable VPN passthrough.
If you have a client PC that cannot run Internet applications properly from behind the EH100, then you can set the
client up for unrestricted Internet access. It allows a computer to be exposed to the Internet. This feature is useful for
gaming purposes. Enter the IP address of the internal computer that will be the DMZ host. Adding a client to the DMZ
(Demilitarized Zone) may expose your local network to a variety of security risks, so only use this option as a last
resort.
VPN Passthrough is enabled by
default for PPTP, L2TP, and IPSec
VPN connections.
This allows VPN
sessions to be established from the LAN
succesfully through the NAT router.

Advanced Wireless Settings
This section contains advanced wireless configuration options. It is recommended that these options remain at their
default values, as improperly adjusting them can have a negative effect on your wireless network perfomance. If you
want to modify these settings and are unfamiliar with them, refer to the explainations below or the Support menu of
the router.

Section ² - Configuration
TX Rate:
Select the basic transfer rates based
on the speed of wireless adapters on
your wireless network. It is strongly
recommended to keep this setting to
Auto
.
Transmit Power:
Set the transmit power of the antennas.
Beacon Interval:
Beacons are packets sent by an Access
Point to synchronize a wireless network.
Specify a value. 100 is the default setting
and is recommended.
RTS Threshold:
This value should remain at its default
setting of 2432. If inconsistent data flow
is a problem, only a minor modification
should be made.
Fragmentation:
The fragmentation threshold, which is specified in bytes, determines whether packets will be fragmented. Packets exceeding
the 2346 byte setting will be fragmented before transmission. 2346 is the default setting.
DTIM Interval:
(Delivery Traffic Indication Message) 3 is the default setting. A DTIM is a countdown informing clients of the next window
for listening to broadcast and multicast messages.
Preamble Type:
Select Short or Long Preamble. The Preamble defines the length of the CRC block (Cyclic Redundancy Check is a common
technique for detecting data transmission errors) for communication between the wireless router and the roaming wireless
network adapters. Auto is the default setting. Note: High network traffic areas should use the shorter preamble type.
CTS Mode:
WMM Function:
CTS (Clear To Send) is a function used to minimize collisions among wireless devices on a wireless local area network (LAN).
CTS will make sure the wireless network is clear before a wireless client attempts to send wireless data. Enabling CTS will
add overhead and may lower wireless through put.
None:
CTS is typically used in a pure 802.11g environment. If CTS is
set to “None” in a mixed mode environment populated by 802.11b clients, wireless collisions may occur frequently.
Always:
CTS will always be used to make sure the wireless LAN is clear before sending data.
Auto:
CTS will monitor the
wireless network and automatically decide whether to implement CTS based on the amount of traffic and collisions that
occurs on the wireless network.
WMM is QoS for your wireless network. Enable this option to improve the quality of video and voice applications for your
wireless clients.
