User Guide
12.3 Firewall Configuration
The following settings will be displayed if you select
Firewall
from the
Configuration
menu.
High
High security level only allows basic Internet functionality. Only Mail, News, Web, FTP, and
IPSEC are allowed. All other traffic is prohibited.
Medium
Factory Default = MEDIUM
Like High security, Medium security only allows basic Internet functionality by default. However,
Medium security allows customization through NAT configuration so that you can enable the traffic
that you want to pass.
Low
The Low security setting will allow all traffic except for known attacks. With Low security, your
Router is visible to other computers on the Internet.
None
Firewall is disabled. (All traffic is passed)
Custom
Custom is an advanced configuration option that allows you to edit the firewall configuration
directly. NOTE: only the most advanced users should try this.
If you select
Edit
from the
Security Level
screen, the
User Defined Firewall Rules
screen will be displayed. This
screen allows you to change the security parameters on your Inbound and Outbound Firewall rules via the
User
Defined Firewall Rules
drop-down arrow. If you select
Inbound
, this will restrict inbound traffic from the WAN to
the LAN.
Outbound
restricts outbound traffic to the WAN from the LAN. To apply the new settings, click
Apply
in
the
screen labeled
User Defined Firewall Rules
.
NOTE
: Westell recommends that you do not change the settings in the
User Defined Firewall Rules
screen. If you
need to reset the Router to factory default settings, push the reset button on the rear of the Router.
