Modem Firewall. The default ‘Firewall On’ setting blocks all anonymous Internet

trafc. Access control enables the user to selectively direct such trafc, for example

to a Web Host in the DMZ or to specic ports opened for such applications as Web,

Telnet or FTP.

CAUTION: This dialog box indicates that you should not disable LAN Web Access

or else you might not be able to connect to the device. If you become

locked out of the device perform a Restore Factory Default as detailed

earlier in this manual.

To congure Access Control, click on Advanced>Access Control. This will reveal the

Enable Access Control screen. The default conguration enables Telnet, Web, FTP

and SSH access FROM the LAN TO the WAN. Access FROM the WAN to the LAN is

not available in the default conguration.

Enable Access Control: check this box to enable selective access from the WAN to

your LAN for applications of the class indicated by the relevant check boxes. If Ac-

cess Control is not enabled, the individual check boxes cannot be checked.

If Access Control is enabled, and an Enable WAN checkbox is selected, then WAN

access to the matching service is enabled. In other words, for example, if your

were to enable Telnet access on the WAN you could then manage and congure

your modem from anywhere on the Internet via Telnet.

Caution: Enabling WAN access to your modem reduces security.

IP Access List: This enables you to specify which LAN/WAN IP addresses are allowed

access to the modem conguration services specied.
