Firewall

The ADSL Wireless Modem Router's firewall inspects packets at the application layer, maintains TCP and UDP session information including time-outs and the number of active sessions, and provides the ability to detect and prevent certain types of network attacks.

Network attacks that deny access to a network device are called Denial-of-Service (DoS) attacks. DoS attacks are aimed at devices and networks with a connection to the Internet. Their goal is not to steal information, but to disable a device or network so users no longer have access to network resources.

The ADSL Wireless Modem Router firewall function protects against the following DoS attacks: IP Spoofing, Land Attack, Ping of Death, IP with zero length, Smurf Attack, UDP port loopback, Snork Attack, TCP null scan, and TCP SYN flooding.

The firewall does not significantly affect system performance, so we advise leaving it enabled to protect your network. Select Enable and click the ‘SAVE SETTINGS’ button to open the Firewall submenus.

Access Control allows users to define the outgoing traffic permitted or not-permitted through the WAN interface. The default is to permit all outgoing traffic.

MAC Filter

The ADSL Wireless Modem Router can also limit the network access based on the MAC address. The MAC Filtering Table allows the ADSL Wireless Modem Router to enter up to 32 MAC addresses that are not allowed access to the WAN port.

1Click Yes to enable, or No to disable this function.

2Enter the MAC address in the space provided and click ‘Save Settings’ to confirm.

URL Blocking

The ADSL Wireless Modem Router allows the user to block access to web sites by entering either a full URL address or just a keyword. This feature can be used to protect children from accessing violent or pornographic web sites.
