Rules List:

The Inbound Filter option is an advanced method of controlling data received from the Internet. With this feature you

can conﬁgure inbound data ﬁltering rules that control data based on an IP address range.

Inbound Filters can be used

with Virtual Server, Port Forwarding, or Remote Administration features.

SPI (Stateful Packet Inspection, also known as dynamic packet

ﬁltering) helps to prevent cyber attacks by tracking more state per

session. It validates that the trafﬁc passing through the session

conforms to the protocol.

Select one of the following for TCP and UDP ports:

Endpoint Independent

- Any incoming trafﬁc sent to an open port

will be forwarded to the application that opened the port. The port

will close if idle for 5 minutes.

Address Restricted

- Incoming trafﬁc must match the IP address

of the outgoing connection.

Address and Port Restriction

- Incoming trafﬁc must match the

IP address and port of the outgoing connection.

Enable this feature to protect your network from certain kinds of

“spooﬁng” attacks.

If an application has trouble working from behind the router, you

can expose one computer to the Internet and run the application on

that computer.

Note:

Placing a computer in the DMZ may expose

that computer to a variety of security risks. Use of this option is only

recommended as a last resort.

Specify the IP address of the computer on the LAN that you want to

have unrestricted Internet communication. If this computer obtains

it’s IP address automatically using DHCP, be sure to make a static

reservation on the Basic > DHCP page so that the IP address of

the DMZ machine does not change.

Enable this feature to allow the router’ NAT to track application that uses protocols other than UDP, TCP or ICMP.

Section ² - Conﬁguration

Application Level Gateway (ALG) Conﬁguration

Here you can enable or disable ALG’s. Some protocols and applications require special handling of the IP payload to

make them work with network address translation (NAT). Each ALG provides special handling for a speciﬁc protocol

or application. A number of ALGs for common applications are enabled by default.

Allows multiple machines on the LAN to connect to their corporate network using PPTP protocol.

Allows multiple VPN clients to connect to their corporate network using IPSec. Some VPN clients support traversal of IPSec

through NAT. This ALG may interfere with the operation of such VPN clients. If you are having trouble connecting with your

corporate network, try turning this ALG off. Please check with the system adminstrator of your corporate network whether

your VPN client supports NAT traversal.

Allows applications that use Real Time Streaming Protocol to receive streaming media from the internet. QuickTime and

Real Player are some of the common applications using this protocol.

Allows all of the Windows/MSN Messenger functions to work properly through the router.

Allows FTP clients and servers to transfer data across NAT. Refer to the Advanced > Virtual Server page if you want to

host an FTP server.

Allows Microsoft NetMeeting clients to communicate across NAT. Note that if you want your buddies to call you, you should

also set up a virtual server for NetMeeting. Refer to the

Advanced

>

Virtual Server

page for information on how to set up

a virtual server.

Allows devices and applications using VoIP (Voice over IP) to communicate across NAT. Some VoIP applications and devices

have the ability to discover NAT devices and work around them. This ALG may interfere with the operation of such devices.

If you are having trouble making VoIP calls, try turning this ALG off.

Allows Ethernet network adapters with Wake-On-LAN (WOL) to function.

Allows Windows Media Player, using MMS protocol, to receive streaming media from the Internet.

Enter the IP address of packets that will take

this route.

Enter the netmask of the route, please note

that the octets must match your destination

IP address.

Enter your next hop gateway to be taken if this

route is used.

The route metric is a value from 1 to 16 that

indicates the cost of using this route. A value 1

is the lowest cost and 15 is the highest cost.

Select the interface that the IP packet must

use to transit out of the router when this route

is used.

Set the transmit power of the antennas.

Beacons are packets sent by an Access Point to

synchronize a wireless network. Specify a value.

100 is the default setting and is recommended.

This value should remain at its default setting of

2346. If inconsistent data ﬂow is a problem, only

a minor modiﬁcation should be made.

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.

(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.

This enables 802.11d opration. 802.11d is a wireless speciﬁcation developed to allow implementation of wireless networks in

countries that cannot use the 802.11 standard. This feature should only be enabled if you are in a country that requires it.

WMM is QoS for your wireless network. This will improve the quality of video and voice applications for your wireless

clients.

Check this box to reduce the guard interval time therefore increasing the data capacity.

However, it’s less reliable and may

create higher data loss.
