Advanced Features 

This Chapter explains when and how to use the ADSL Wireless Fire-
wall Router's "Advanced" Features. 

Overview 

The following advanced features are provided: 

• 

Internet: 

• 

DMZ 

• 

URL filter 

• 

Dynamic DNS 

• 

Firewall Rules 

• 

Firewall Services 

• 

Schedule  

• 

Virtual Servers 

Internet 

This screen provides access to the DMZ and URL Filter features. 

 

Figure 27: Advanced Internet Screen 

DMZ 

This feature, if enabled, allows the DMZ computer on your LAN to be exposed to all 
users on the Internet.  

• 

This allows almost any application to be used on the "DMZ PC". 

• 

The "DMZ PC" will receive all "Unknown" connections and data. 

• 

If the DMZ feature is enabled, you must select the PC to be used as the "DMZ PC". 

 

 

The "DMZ PC" is effectively outside the Firewall, mak-
ing it more vulnerable to attacks. For this reason, you 
should only enable the DMZ feature when required.
