Applications
You can add the applications of your choice to the predefined “Current Applications” list.
To do
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
“Current Applications” list.

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.
5.6
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.

Other Settings

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
”.

whether the PC is connected directly (via the Ethernet port) or remotely (by a switch, hub or access
point) to the AirTies RT-205. The download and upload totals are for all Internet
traffic that goes
through the RT-205.
