Advanced_WEB Filter

This section is where you add the Web sites to be used for Access Control. The Web sites

listed here are used when the Web Filter option is enabled in

Access Control

.

The Web Filter section is one of two means by which you can specify the web sites you want

to allow. You also have the alternative of using the Sentinel Parental Controls Service, which

allows you to specify broad categories of web sites and saves you the trouble of entering

specific web site URLs. For more information about the Sentinel service, refer to

Web Filter Parameters

Web Site

Enter the address of the web site that you want to allow; for example:

google.com

. Do not enter the

http://

preceding the address. Enter the most

inclusive domain; for example, enter

u-media.com

and access will be permitted

to both

www.u-media.com

and

support.u-media.com

.

Many web sites construct pages with images and content from other

web sites. Access will be forbidden if you do not enable all the web

sites used to construct a page. For example, to access

46

my.yahoo.com

, you need to enable access to

yahoo.com

,

yimg.com

, and

doubleclick.net

.

Advanced_MAC Address Filter

The MAC address filter section can be used to filter network access by machines based on

the unique MAC addresses of their network adapter(s). It is most useful to prevent

unauthorized wireless devices from connecting to your network. A MAC address is a unique

ID assigned by the manufacturer of the network adapter.

Enable MAC Address Filter

When this is enabled, computers are granted or denied network access depending

on the mode of the filter.

Misconfiguration of this feature can prevent any machine from accessing

the network. In such a situation, you can regain access by activating the

factory defaults button on the router itself.

Filter Settings

Mode

When "only allow listed machines" is selected, only computers with MAC

addresses listed in the MAC Address List are granted network access. When

clients.

Advanced_Firewall

The router provides a tight firewall by virtue of the way NAT works. Unless you configure the

router to the contrary, the NAT does not respond to unsolicited incoming requests on any

port, thereby making your LAN invisible to Internet cyber attackers. However, some network

applications cannot run with a tight firewall. Those applications need to selectively open

ports in the firewall to function correctly. The options on this page control several ways of

opening the firewall to address the needs of specific types of applications. See also
