Access Control
Use Access Control to configure advanced security functions by customising the NB4
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 Factory Default Reset as detailed on page 16 of this manual.
To configure Access Control, click on Advanced>Firewall>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.
