	“homepage” connection button. When this is set to auto, the Router will monitor
	the network traffic and determine when a connection needs to be made. The
	connection process will happen automatically the “Always ON” selection causes

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.
