NAT (Network Access Translation)

The NAT feature provides the basic firewall feature to avoid hacker attacks from

remote site. There are three more setting pages including virtual server, port trigger,

and DMZ to provide specified service for remote users.

Virtual Server

Virtual Server enables you to run a server on your local network that can be accessed

from the remote parties. You need to set up a rule to tell the device on which computer

the server is held. When port virtual server is enabled, your router (the device) routes

all the inbound traffic on a particular port to the chosen computer on your network.

Click Add to add a rule of virtual server.

Port Triggering

The feature is similar to the virtual server, but provides a more secure way to provide

your device. It opens up the port hole temporary and allows CPE in LAN to establish a

connection with remote parties. Those ports are open only if a specified request from

a PC in LAN is received, and then the device allows the remote parties to access to

establish a connection with that PC in LAN.
