Field Name 
Description 
Port Forwarding 
Use this page to configure port forwarding for local IP 
addresses. Port forwarding allows you to run a server 
on the local area network (LAN) by specifying the 
mapping of TCP/UPD ports to local PCs or to the IP 
address of other devices. This is a static setting that 
holds the ports open at all times 
Port Triggers 
Use this page to configure TCP/UPD port triggers. 
Port triggering is similar to port forwarding, but is a 
dynamic function. In other words, the ports are not 
held open, and the ports close if no outgoing data is 
detected on the selected ports for a period of 10 
minutes 
DMZ Host 
(Demilitarized Zone) 
Use this page to configure an IP address that is visible 
to the wide area network (WAN). DMZ hosting is 
commonly referred to as “exposed host,” and allows 
you to specify the “default” recipient of WAN traffic 
that Network Address Translation (NAT) is unable to 
translate to a known local PC.  
A DMZ is used by a company that wants to host its 
own Internet services without sacrificing unauthorized 
access to its private network. DMZ allows one IP 
address to be unprotected while others remain 
protected. The DMZ is located between the Internet 
and an internal network’s line of defense that is a 
combination of firewalls and bastion hosts. 
Typically, the DMZ contains devices accessible to 
Internet traffic, such as Web (HTTP) servers, FTP 
servers, SMTP (e-mail) servers, and domain name 
system (DNS) servers
