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

Use this page to configure an IP address that is visible

(Demilitarized Zone)

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
