this, go to

“Applications” under the “FIREWALL” menu on the left menu bar of the Web interface.

In this window,

you can add/remove definitions of the special programs, games and P2P software

that can be used by the IP filters, or you can change the port numbers of the existing applications.

To add a new application to the “Current Applications” list click the “New” button. Enter the name

of the application in “Application

Name” field, external port number in the “Real Ports” field, and

internal port number in the “LAN Ports” field. Click “Save”.

The rule / application you have defined is now added to the

MAC Address Filtering

MAC Address Filtering allows you to permit network access based on MAC addresses. When this

feature is activated, you can specify the MAC addresses of the computers that will be allowed

access to the internet.

To activate the MAC Address filtering feature, go to “MAC Address Filtering” under the “FIREWALL”

menu on the left menu bar of the AirTies RT-205 Web interface.

•

Check the “Activate MAC Address Filtering” box.

•

Enter the MAC address of the computer you would like to allow Internet access to in the “Add

New MAC Address” field (e.g. 00:12:34:56: ab: cd). You can also browse the “Clients List” and

select the MAC addresses to be added from there.

•

Click “Add”. This will add the MAC address to the “Blocked Clients list”. The entries in the

“Filtered Clients” list will be granted access to the Internet.

In order to find out the MAC address of the Ethernet card or the wireless adapter of a computer,

enter “ipconfig /all” in the DOS command line.

5.4

Web Filtering

With the Web Filtering feature, you can block some possibly risky web based application features

before they reach the computers in your network. For example: cookies can cause your personal

information to be obtained since they contain website entry information.

To define web filters, go to “Web Filters” under the “FIREWALL” menu on the left menu bar of

the AirTies RT-205 web interface. For each web application feature you would like to block (proxy,

cookie, java applet, activeX, pop-up), check the corresponding “Filter On” box.

URL Filters

You can block access of any computer in your local network to certain websites. To define the

websites that you do not want users to access:

•

Go to “URL Filters” under the “FIREWALL” menu on the left menu bar of the web interface.

•

Specify the URL or any keyword that is part of a URL in the “URL Filters” window. For example,

when “mars” is entered as a URL keyword, access to both www.marslilartraveltomars.com and

www.marslilardunyadalifeonmars.com will be blocked.

•

To block access of a computer in your local network to any of these sites, check “Http with URL

Filters” box for the rule that you created for this computer in the “Access Control” page.

DMZ

DMZ (Demilitarized Zone) opens up all the ports of a single local network host for unrestricted

access from the Internet.

Although it’s a risky method, you can open and forward all the ports for a certain client at once

with DMZ to resolve access problems resulting from firewall or NAT settings.

WARNING: It is not recommended to keep all the ports open for any client for an extended period.

To enable DMZ:

1- Go to “

DMZ

” under the “

FIREWALL

” menu on the left Menu bar.

2- Check the “

Activate DMZ

” box.

3- Enter the local IP address of the client that you would like traffic to be forwarded to in the

“

Select LAN IP Address

” field and click “

Save

”.

This way, all data packets directed to the global IP address of your RT-205, (i.e. your legal IP

address on the Internet) will be forwarded to this local client, regardless of the port number.

NAT (Network Address Translation) and

Port Forwarding Settings

Network Address Translation (NAT) is a way to map an entire network (or networks) to a single

IP address. NAT allows multiple users in your local network to access the Internet through a

single public IP address (the global or legal IP address) assigned to you by your Internet service

provider. While your WAV-140 bears the global IP address, local IP addresses (like 192.168.2.4)

are assigned to hosts on your local network.

For a host outside your local network to access a machine on your local network, “Port Forwarding”

is used. Data packets sent from the Internet to your global IP address arrive at a certain port of

your modem. If Port Forwarding is defined for that port, the incoming traffic is redirected to a

machine inside the local network that has only a local IP address.

Some popular peer-to-peer

applications (e.g. E-mule, Kazaa, VPN, Remote desktop) rely on this technology.

To enable Port Forwarding on a port, go to

“

NAT

” menu on the left menu bar and click on “

Port

Forwarding”

.

In the window titled “Port Routing”, you can either find and select the client machine from the

list of machines on the local network and the application from the “Current Applications” list, or

you can enter a new application, and related forwarding information.

In the window titled “Port Routing”:

•

In the “

Application

” field, assign a name for the Port Forwarding rule you are creating.

•

Enter the local IP address of the client that is to be accessible from the Internet in the “

Target

IP Address

” field.

•

Select the protocol that the application uses from the list of protocols in the “

Protocol

” box. If

you are unsure of the protocol, select “TCP&UDP”.

•

Enter the real port number used by the application in the “

Wan Ports

” field.

•

Enter the local port number for the application in the “

Target LAN Ports

” field. (can be the same

as the Real Port)

•

To forward a range of ports instead of a single port, use a dash (-) sign in between. For example

to forward all ports between 23 and 80, enter “23-80”.

•

Check the “

Enable

” box.

Click “

Save

”.
