Modem Firewall. The default ‘Firewall On’ setting blocks all anonymous Internet
traffic. Access control enables the user to selectively direct such traffic, for example
to a Web Host in the DMZ or to specific 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 configure Access Control, click on Advanced>Access Control. This will reveal the
Enable Access Control screen. The default configuration 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 configuration.
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 configure
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 configuration services specified.
