Advanced IDS Page

The CH6640E/CG6640E IDS Pages allow you to configure the CH6640E/CG6640E

firewall filters and firewall alert notifications. The CH6640E/CG6640E firewall protects the

CH6640E/CG6640E 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-of-service 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:

•

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

CH6640E/CG6640E LAN. The CH6640E/CG6640E 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 CH6640E/CG6640E 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 CH6640E/CG6640E Configuration

Manager.

GATEWAY Wireless Pages

The CH6640E/CG6640E Wireless Pages allow you to configure your wireless LAN

(WLAN).

You can click any Wireless submenu option to view or change the configuration

information for that option. WPA or WPA2 encryption provides higher security than WEP

encryption, but older wireless client cards may not support the newer WPA or WPA2

encryption methods.

Wireless Band Mode Page

CH6640E/CG6640E is a single band product, Select 2.4GHz if you want to use the

2.4GHz band, select Turn Off will disable wireless, and you cannot associate with AP

through wireless.

Wireless Basic Page

This page allows you to configure basic features of your Wi-Fi wireless network. You can

enable or disable the wireless interface, hide the network from active scans, set the

wireless network name (also known as SSID) and select the working channel.

Field Descriptions for the Wireless Basic Page

Field

Description

SSID

Sets the Network Name (also known as SSID) of the Primary

wireless network. This is a 1-32 ASCII character string.

Hide Network

With a hide network, users type the SSID into the client

application instead of selecting the SSID from a list. This feature

makes it slightly more difficult for the user to gain access.

WMM

Enabling WMM can help control latency and jitter when

transmitting multimedia content over a wireless connection.

Bridge

When the check box set, indicates network traffic from which

particular wireless interface will be bridged to HFC interface.

When the checkbox cleared, indicates network traffic from which

particular wireless interface will be handled by Gateway routing

features.

Enable

Enable or disable this wireless interface.

Transmission Mode

Select which 802.11 mode is used by CH6640E/CG6640E,

including 802.11b/g/n mixed mode, 802.11n only, 802.11b/g

mixed mode.

Channel Width

Select the channel width (20 MHz or 20/40 MHz) to be used by

CH6640E/CG6640E. When 20/40MHz is selected 802.11n

clients experience improved throughput using 40 MHz, while

legacy clients(either 802.11a or 802.11b/g) can still be serviced

without interruption using 20MHz.

Primary Channel

Select primary (control) channel is in the lower or upper 20 MHz

band of the bonded 40 MHz channel.

Channel

Select the current channel number or control channel, you can

select “Select Best Quality Channel Automatically” check box to

auto select one, this value depend on Transmission Mode.

Transmission Rate

Select 802.11 physical transmission rate, this value depends on

Transmission Mode.

Multicast Rate

Select the physical layer transmission rate used for Multicast

traffic

on

the

wireless

interface,

this

value

depend

on

Transmission Mode.

Wireless Security Page

This page allows you to protect your Wi-Fi wireless network by specifying WEP, 802.1x,

WPA, or WPA2 wireless security. Before setting up security, ensure that your wireless

adaptors support the same type of security.

The default type of security is Mixed WPA-PSK/WPA2-PSK. Field of Mixed WPA-

PSK/WPA2-PSK, WPA2-PSK and WPA-PSK are the same.
