Firewall Settings

This screen is an advanced configuration screen. It allows you to set the level of security you wish to have on your local network. All security levels except “None” protect against known Internet attacks and devices that attempt to gain remote access to your Router. The following settings are displayed.

	Firewall Settings
High	This security level only allows basic Internet functionality. Only Mail, News,
	Web, FTP, and IPSEC are allowed. No other traffic is allowed. Another
	restriction of high security is that it can’t be modified by NAT configuration
	options. With High security, you are guaranteed to only pass the previously
	mentioned traffic.
Medium	This security level only allows basic Internet functionality by default. Like High
	security, Medium security, allows customization through NAT configuration, so
	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 by other computers on the Internet.
Custom	Custom is a very advanced configuration option that allows you to edit the
	firewall configuration directly. Only the most expert users should try this.

Home Page

The home page gives you a quick summary of the Router’s state. The following settings are displayed.

	Home Page
Connection Overview	The Connection Overview section displays the status of the DSL connection.
	The DSL must show a state of “UP” in order for the Router to communicate
	with your service provider’s network.
Connection Name	The Connection Name section displays all of the connection profiles that are
	defined by the Router. A connection profile is information that the Router needs
	to establish a connection to your ISP. The “PPP Status” columns will show a
	status of “UP” if the Router is currently using that profile to communicate. The
	command button allows you to control the connection state.
Profile Editor	Selecting the “Profile Editor” link will allow you to define or change any of the
	connection profile settings.
