General Firewall Settings
Maximum Security
(High)
High security level only allows basic Internet functionality. Only Mail, News, Web,
FTP, and IPSEC are allowed. All other traffic is prohibited.
Typical Security
(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.
Minimum Security
(Low)
Low security setting will allow all traffic except for known attacks. With Low
security, your Router is visible to other computers on the Internet.
No Security
(None)
Factory Default = No Security (None)
The Firewall is disabled. (All traffic is passed)
Custom Security
(Custom)
Custom is a security option that allows you to edit the firewall configuration directly.
Note: Only the most advanced users should try this.
15.2 Editing Firewall Security Rules
To edit the firewall security rules and customize them to your preference, in the General screen, click Edit. If no
security rules have been previously configured, the following pop-up screen will appear. Click OK in the pop-up
screen. At the General screen, select the security option that want to edit, and then click Apply.
Next, select the Custom Security (None) option in the General screen, and then click Apply. Click Edit to go to
the User Defined Firewall Rules screen and edit the security rules for the security option you selected (High,
Medium, Low, None) in the General screen.
IMPORTANT:
1. Custom Security is a very advanced configuration option that allows you to edit the firewall configuration
directly. Only expert users should attempt this. It is recommended that you do not change the settings in this
screen. If you need to reset your Router to factory default settings, push the reset button on the rear of the Router.
Or follow the instructions in section 16.2, “Restore Defaults,” to restore the Router to default settings.
2. If you need help, click Main in the top navigational menu to go to the home page, and then click Verizon Help to
access Verizon’s Online Help Web site for your DSL Router.
The User Defined Firewall Rules screen allows you to configure the security parameters on your Inbound and
Outbound traffic. Inbound rules will restrict inbound traffic from the WAN to the LAN. Outbound rules will restrict
outbound traffic from the LAN to WAN. Enter the desired parameters, click Save, and then click Apply to allow the
settings to take effect in your Router.
NOTE: Clicking Save allows the firewall rules to be saved to flash (a temporary storage area in your Router).
