Incoming traffic from the Internet is normally discarded by the Firewall unless the traffic is a 
response to one of your local computers or a service that you have configured in the Ports menu. 
Instead of discarding this traffic, you can have it forwarded to one computer on your network. This 
computer is called the Default DMZ Server.
To assign a computer or server to be a Default DMZ server: 
1.
Click Default DMZ Server. 
2.
Type the IP address for that server. 
3.
Click Apply. 
Enabling Access to Local Servers Through a FVS318
Although the Firewall causes your entire local network to appear as a single machine to the 
Internet, you can make local servers for different services (for example, FTP or HTTP) visible and 
available to the Internet. This is done using the Ports menu. 
When a remote computer on the Internet wants to access a service at your IP address, the requested 
service is identified by a port number in the incoming IP packets. For example, a packet that is sent 
to the external IP address of your Firewall and destined for port number 80 is an HTTP (Web 
server) request. Many service port numbers are already defined in a Services list in the Ports menu, 
although you are not limited to these choices. See IETF RFC1700, “Assigned Numbers,” for port 
numbers for common protocols. Use the Ports menu to configure the Firewall to forward incoming 
traffic to IP addresses on your local network based on the port number.
Remember that port forwarding opens holes in your firewall. Only enable those ports that are 
necessary for your network.
How to Configure Port Forwarding to Local Servers
1.
Log in to the Firewall at its default LAN address of 
http://192.168.0.1
 with its default User 
Name of 
admin
, default password of 
password
, or using whatever User Name, Password and 
LAN address you have chosen for the Firewall.
Note: 
Some residential broadband ISP accounts do not allow you to run any server 
processes (such as a Web or FTP server) from your location. Your ISP may periodically 
check for servers and may suspend your account if it discovers any active services at 
your location. If you are unsure, refer to the Acceptable Use Policy of your ISP.
