Allow Internet
access to be
disabled
• If checked, then UPnP users can disable Internet access via this
device.
• If Disabled, UPnP users can NOT disable Internet access via this
device. But currently, this restriction only applies to users running
Windows XP, who access the Properties via UPnP. (e.g. Right -
click the LevelOne Broadband Router in My Network Places, and
select Properties)
Firewall
Enable DoS
Firewall
If enabled, DoS (Denial of Service) attacks will be detected and blocked.
The default is enabled. It is strongly recommended that this setting be
left enabled.
Note:
• A DoS attack does not attempt to steal data or damage your PCs,
but overloads your Internet connection so you can not use it - the
service is unavailable.
• The LevelOne Broadband Router uses "Stateful Inspection"
technology. This system can detect situations where individual
TCP/IP packets are valid, but collectively they become a DoS at-
tack.
Threshold
This setting affects the number of "half-open" connections allowed.
• A "half-open" connection arises when a remote client contacts the
Server with a connection request, but then does not reply to the
Server's response.
• While the optimum number of "half-open" connections allowed
(the "Threshold") depends on many factors, the most important
factor is the available bandwidth of your Internet connection.
• Select the setting to match the bandwidth of your Internet connec-
tion.
