Configuring the Wireless Router
14
RIP Defect (Default : Disabled) - If an RIP request packet is not 
acknowledged to by the router, it will stay in the input queue and not 
be released. Accumulated packets could cause the input queue to fill, 
causing severe problems for all protocols. enabling this feature prevents 
the packets from accumulating.
Discard Ping to WAN (Default : Disabled) - Prevent a ping on the 
Wireless Router’s WAN port from being routed to the network.

Stateful Packet Inspection
This is called a "Stateful" packet inspection because it examines the 
contents of the packet to determine the state of the communications ; 
i.e., it ensures that the stated destination computer has previously 
requested the current communication. This is a way of ensuring that all 
communications are initiated by the recipient computer and are taking 
place only with sources that are known and trusted from previous 
interactions. In addition to being more rigorous in their inspection of 
packets, stateful inspection firewalls also close off ports until connection 
to the specific port is requested.
When particular types of traffic are checked, only the particular type of 
traffic initiated from the internal LAN will be allowed. For example, if 
the user only checks "FPT Service" in the Stateful Packet Inspection 
section, all incoming traffic will be blocked except for FTP connections 
initiated from the local LAN.
Stateful Packet Inspection allows you to select different application 
types that are using dynamic port numbers. If you wish to use the 
Stateful Packet Inspection (SPI) to block packets, click on the Yes radio 
button in the "Enable SPI and Anti-DoS firewall protection" field and 
then check the inspection type that you need, such as Packet 
Fragmentation, TCP Connection, UDP Session, FTP Service, H.323 
Service, or TFTP Service.
When hackers attempt to enter your network, the router can alert 
you by e-mail
If the mail server needs to authenticate your indentification before 
sending out any e-mail, please fill related information in POP3 server, 
username and password fields. Otherwise leave the three fields blank.
Connection Policy
Enter the appropriate values for TCP/UDP sessions as described in the 
following table.
Note
The firewall does not significantly affect system performance, so we 
advise enabling the prevention features to protect your network.
4.8.6
DMZ
If you have a client PC that cannot run an Internet application properly 
from behind the firewall, you can open the client up to unrestricted 
two-way Internet access. Enter the IP address of a DMZ (Demilitarized 
Zone) host on this screen. Adding a client to the DMZ may expose your 
local network to a variety of security risks, so only use this option as a 
last resort.
4.9
UPnP
UPNP (Universal Plug and Play) settings
With Universal Plug and Play, a device can automatically join a network, 
obtain an IP address, communicate its capabilities, and learn about the 
presence and capabilities of other devices. Devices can then directly 
communicate with each other. This further enables peer-to-peer 
networking.
4.10 DDNS
DDNS (Dynamic DNS) settings
DDNS text "Domain Name" is a series of alphanumeric strings 
separated by periods that maps to the address of a network connection 
and identifies the owner of the address.
Dynamic DNS provides users on the Internet with a method to tie their 
domain name to a computer or server. DDNS allows your domain 
name to follow your IP address automatically by having your DNS 
records changed when your IP address changes.
The Server Configuration section automatically opens the TCP port 
options checked in the Virtual Server section. Simply enter in the IP 
Address of your server, such as a web server, and then click on the port 
option HTTP Port 80 so users can access your web server from the 
Internet connection.
This DNS feature is powered by a DDNS service provider. With 
a DDNS connection you can host your own web site, email server, FTP 
site, and more at your own location even if you have a dynamic IP 
address. (Default : Disable)
