Special AP
Some applications like On-line games, Video conferencing and Internet telephony require multiple connections to the internet. As
such, these applications cannot work with a pure NAT router such as the NP805N.
The Special Applications feature allows some of these applications to work with this router.
Please Note: If this fails to make the application work, try to set up that computer as the DMZ host instead.
(For further instructions on setting up a DMZ host, please refer to the “Miscellaneous” section below)
OPTION
DEFINITION
Trigger
The outbound port number that will be triggered by the application..
Incoming Ports
When the trigger packet is detected, the inbound packets sent to the specified port numbers will be allowed to pass through the
firewall.
Enable
Select to enable or disable the configured special application entry.
The NP805N also provides predefined settings for some popular applications.
To use the predefined settings, select your application from the Popular application pull down ist, select an unused ID from the list
and then click Copy to. The predefined settings will then be added to the list.
Click "Save" to save the settings or "Undo" to cancel.
Miscellaneous
A Demilitarized Zone (DMZ) Host is a computer without the protection of firewall. It allows that particular computer to be exposed to
unrestricted 2-way communication to the internet. It is mostly used for Internet games, Video conferencing, Internet telephony and
other special applications.
To enable DMZ, enter the IP address of the computer you
want to be live on the internet and click on “
Enable
”.
Please Note: This feature should be used only when necessary.
OPTION
DEFINITION
IP Address of DMZ Host
Enter the IP address of the computer you wish to put in the DMZ.
UPnP Setting
The device also supports uPnP. If the DMZ host operating system supports this function enable it to automatically configure the
required network settings.
Click "Save" to save the settings or "Undo" to cancel.

Packet Filters
The Packet Filter enables you to control what packets are allowed to pass through the router. There are two types of packet filter,
Outbound Packet Filter which applies to all outbound packets and the Inbound Packet Filter which only applies to packets that are
destined for a Virtual Server or DMZ host only.
Please note: For further instructions on setting up MAC Level Filtering, please refer to
the “MAC Control” section below
Outbound Filter:
To enable an Outbound Filter, tick the “Enable” tick box at the top of the page.
There are two types of filtering policies:
Allow all data traffic to pass except those that match the specified rules.
Deny all data traffic to pass except those that match the specified rules.
You can specify up to 48 filtering rules for each direction (Inbound or Outbound). For each rule you will need to define the following:
Source IP address
Source port
Destination IP address
Destination port
Protocol: TCP or UDP or both.
Use Schedule Rule#
For source or destination IP address, you can define a single IP address (192.168.20.1) or a range of IP addresses
(192.168.20.100-192.168.20.200). Leaving these fields empty implies all IP addresses are matched.
For source or destination port, you can also define a single port (80) or a range of ports (1000-1999). Use the prefix "T" or "U" to
specify either the TCP or UDP protocol e.g. T80, U53, U2000-2999. No prefix indicates both
TCP and UDP are defined. Leaving this field empty implies all ports are matched.
The Packet Filter also works with Scheduling Rules, and gives you more flexibility on Access control.
Please note:
For further instructions on scheduling rules, please refer to the “Scheduling” section later in
this guide
