Using the Configuration Utility (continued)
Advanced > Virtual Server
The DWL-1750 can be configured as a Virtual Server so that remote users accessing
Web and FTP services via the public IP Address can be automatically redirected to local
servers in the LAN (Local Area Network.)
The DWL-1750 firewall feature filters out unrecognized packets to protect your LAN net-
work so all computers networked with the DWL-1750 are invisible to the outside world. If
you wish you can make some of the LAN computers accessible from the Internet by
enabling Virtual Server. Each Virtual Service that is created will be listed at the bottom of
the screen in the Virtual Servers List

SSID Broadcast-
Enable the SSID Broadcast feature to announce the SSID across
the network. Enabling this will allow you to use XP’s site survey
tools. Disabling SSID Broadcast can be a useful security mea-
sure.
Fragmentation-
The fragmentation threshold, which is specified in bytes, deter-
mines whether packets will be fragmented. Packets exceeding
the 1600 byte setting will be fragmented before transmission.
1600 is the default setting.
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 250. If you en-
counter inconsistent data flow, only minor modifications should
be made within the value range of 0-3000.
