ports to the PC on your network running the application. You will also need to use 
port forwarding if you want to host an online game server. The reason for this is that 
when using NAT, your publicly accessible IP address will be used by and point to your 
router, which then needs to deliver all traffic to the private IP addresses used by 
your PCs. Please see the WAN Configuration section of this manual for more 
information on NAT. 
 
BiGuard 30 can also be configured as a virtual server so that remote users accessing 
services such as Web or FTP services via the public (WAN) IP address can be 
automatically redirected to local servers in the LAN network. Depending on the 
requested service (TCP/UDP port number), the device redirects the external service 
request to the appropriate server within the LAN network. 
 
4.4.8.1  DMZ 
 
The DMZ Host is a local computer exposed to the Internet. When setting a particular 
internal IP address as the DMZ Host, all incoming packets will be checked by the 
Firewall and NAT algorithms then passed to the DMZ host, when a packet received 
does not use a port number used by any other Virtual Server entries. 
 
Caution: Such Local computer exposure to the Internet may face a variety of 
security risks. 
 
 
Enable DMZ function: 
 
Enable: Activates your router’s DMZ function. 
 
Disable: Default setting. Disables the DMZ function. 
DMZ IP Address: Give a static IP address to the DMZ Host when the Enable radio 
button is selected. Be aware this IP will be exposed to the WAN/Internet. 
Candidates: You can also select the Candidates which are referred from the ARP
