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.
