You can connect up to 253 client computers to the CH6643E using one or any combination of the following network connections:
Wi-Fi wireless LAN (WLAN)
Ethernet local area network (LAN)
Wireless LAN
Wireless communication occurs over radio waves rather than a wire. Like a cordless telephone, a WLAN uses radio signals instead of wires to exchange data. A wireless network eliminates the need for expensive and intrusive wiring to connect computers throughout the home or office. Mobile users can remain connected to the network even when carrying their laptop to different locations in the home or office.
Each computer or other device on a WLAN must be Wi-Fi enabled with either a built-in or external wireless adapter.
Laptops
— Use a built-in wireless notebook adapter, a wireless PCMCIA slot adapter, or a wireless USB adapter.
Desktops
— Use a wireless PCI adapter, wireless USB adapter, or compatible product in the PCI slot or USB port, respectively.

2. Click Add MAC Address.
3. Repeat above steps for up to twenty MAC addresses.
Advanced Port Filtering Page
This page allows you to define port filters to prevent all devices from sending outgoing
TCP/UDP traffic to the WAN on specific IP port numbers. By specifying a starting and ending port range, you can determine what TCP/UDP traffic is allowed out to the WAN on a per-port basis.
31
Note: The specified port ranges are blocked for ALL PCs, and this setting is not IP address or MAC address specific. For example, if you wanted to block all PCs on the private LAN from accessing HTTP sites
(or
“web surfing”), you would set the “Start Port” to 80, “End Port” to 80,
“Protocol” to TCP, checkmark Enabled, and then click Apply.

Advanced Port Forwarding Page
This page allows you to run a publicly accessible server on the LAN by specifying the mapping of TCP/UDP ports to a local PC. This enables incoming requests on specific port numbers to reach web servers, FTP servers, mail servers, etc. so that they can be accessible from the public Internet.
32
The ports used by some common applications are:
HTTP: 80
FTP: 20, 21
Secure Shell: 22
Telnet: 23
SMTP e-mail: 25
SNMP: 161
To map a port, you must enter the range of port numbers that should be forwarded locally and the IP address to which traffic to those ports should be sent. If only a single port specification is desired, enter the same port number in the
“start” and “end” locations for that IP address.
33
Advanced Port Triggers Page
This page allows you to configure dynamic triggers to specific devices on the LAN. This allows for special applications that require specific port numbers with bi-directional traffic to function properly. Applications such as video conferencing, voice, gaming, and some messaging program features may require these special settings.
The Advanced Port Triggers are similar to Advanced Port Forwarding except that they are not static ports held open all the time. When the Configuration Manager detects outgoing data on a specific IP port number set in the
“Trigger Range,” the resulting ports set in the
“Target Range” are opened for incoming (sometimes referred to as bi-directional ports) data. If no outgoing traffic is detected on the
“Trigger Range” ports for

Advanced DMZ Host Page
This page allows you to specify the default recipient of WAN traffic that NAT is unable to translate to a known local PC. The DMZ (De-militarized Zone) hosting (also commonly referred to as
“Exposed Host”) can also be described as a computer or small sub-network that is located outside the firewall between the trusted internal private LAN and the untrusted public Internet. It prevents direct access by outside users to private data.
For example, you can set up a web server on a DMZ computer to enable outside users to access your website without exposing confidential data on your network.
A DMZ can also be useful to play interactive games that may have a problem running through a firewall. You can leave a computer used for gaming only exposed to the
Internet while protecting the rest of your network.
You may configure one PC to be the DMZ host. This setting is generally used for PCs using problem applications that use random port numbers and do not function correctly with specific port triggers or the port forwarding setups mentioned earlier. If a specific PC is set as a DMZ Host, remember to set this back to zero when you are finished with the needed application, since this PC will be effectively exposed to the public Internet, though still protected from Denial of Service (DoS) attacks via the Firewall.
Setting Up the DMZ Host
1. Enter the computer
’s IP address and select Enable checkbox.
2. Click Apply to activate the selected computer as the DMZ host.
Dynamic DNS
This page allows you to provide Internet users with a name (instead of an IP address) to access your virtual servers. CH6643E supports dynamic DNS service provided by

Advanced IDS Page
The CH6643E IDS Pages allow you to configure the CH6643E firewall filters and firewall alert notifications. The CH6643E firewall protects the CH6643E LAN from undesired attacks and other intrusions from the Internet. It provides an advanced, integrated stateful-inspection firewall supporting intrusion detection, session tracking, and denial-ofservice attack prevention. The firewall:
Maintains state data for every TCP/IP session on the OSI network and transport layers.
Monitors all incoming and outgoing packets, applies the firewall policy to each one, and screens for improper packets and intrusion attempts.
Provides comprehensive logging for all:
36
User authentications
Rejected internal and external connection requests
Session creation and termination
Outside attacks (intrusion detection)
The predefined policies provide outbound Internet access for computers on the CH6643E
LAN. The CH6643E firewall uses stateful-inspection to allow inbound responses when there already is an outbound session running that corresponds to the data flow. For example, if you use a web browser, outbound HTTP connections are permitted on port
80. Inbound responses from the Internet are allowed because an outbound session is established.
When required, you can configure the CH6643E firewall to allow inbound packets without first establishing an outbound session. You also need to configure a port forwarding entry on the Advanced Port Forwarding Page or a DMZ client on the Advanced DMZ Host
Page .
This page allows you to configure the firewall by enabling or disabling various protection features. Block Fragmented IP packets prevent all fragmented IP packets from passing through the firewall. Port Scan Detection detects and blocks port scan activity originating on both the LAN and WAN. IP Flood Detection detects and blocks packet floods originating on both the LAN and WAN.
Checkmark Enable for each Web filter you want to set for the firewall, and then click Apply.
The Web filters will activate without having to reboot the CH6643E Configuration Manager.

Setting Up Your Wireless LAN
You can use the CH6643E as an access point for a wireless LAN (WLAN) without changing its default settings.
To enable security for your WLAN, you can do the following on the CH6643E:
Encrypt wireless LAN transmissions
Restrict wireless LAN access to further prevent unauthorized WLAN intrusions using the Wireless Access Control Page
CAUTION: Never provide your SSID, WPA or WEP passphrase, or
WEP key to anyone who is not authorized to use your WLAN.
Connect at least one computer to the CH6643E Ethernet port to perform configuration.
Do not attempt to configure the CH6643E over a wireless connection.
You need to configure each wireless client (station) to access the CH6643E LAN.
Another step to improve wireless security is to place wireless components away from windows. This decreases the signal strength outside the intended area.

Encrypting Wireless LAN Transmissions
To prevent unauthorized viewing of data transmitted over your WLAN, you must encrypt your wireless transmissions. Choose one of the following:
Encrypting Wireless LAN Transmissions
Configure on the CH6643E Required on Each Wireless Client if all of your wireless clients support Wi-Fi Protected Access
(WPA), recommending configuring
WPA on the CH6643E
If you use a local pre-shared key (WPA-PSK) passphrase, you must configure the identical passphrase on the CH6643E and on each wireless client. Home and small-office settings typically use a local passphrase.
Otherwise, configure WEP on the
CH6643E
You must configure the identical WEP key on the
CH6643E and on each wireless client.
If all of your wireless clients support WPA encryption, recommending using WPA instead of WEP because WPA:
Provides much stronger encryption and is more secure
Provides authentication to ensure that only authorized users can log in to your WLAN
Is much easier to configure
Uses a standard algorithm on all compliant products to generate a key from a textual passphrase
Will be incorporated into the new IEEE 802.11i wireless networking standard
For new wireless LANs, recommending purchasing client adapters that support WPA encryption.
