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,
DMZ and ALG 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.
