Hitron CGNV User’s Guide
Traceroute: this tool allows you to see the route taken by data packets to get
from the CGNV to the destination you specify. You can use this tool to solve
routing problems, or identify firewalls that may be blocking your access to a
computer or service.
4.1.5 Port Forwarding
Port forwarding allows a computer on your LAN to receive specific communications
from the WAN. Typically, this is used to allow certain applications (such as gaming)
through the firewall, for a specific computer on the LAN. Port forwarding is also
commonly used for running a public HTTP server from a private network.
You can set up a port forwarding rule for each application for which you want to open
ports in the firewall. When the CGNV receives incoming traffic from the WAN with a
destination port that matches a port forwarding rule, it forwards the traffic to the LAN
IP address and port number specified in the port forwarding rule.
NOTE: For information on the ports you need to open for a particular application,
consult that application’s documentation.
4.1.6 Port Triggering
Port triggering is a means of automating port forwarding. The CGNV scans outgoing
traffic (from the LAN to the WAN) to see if any of the traffic’s destination ports match
those specified in the port triggering rules you configure. If any of the ports match, the
CGNV automatically opens the incoming ports specified in the rule, in anticipation of
incoming traffic.
4.1.7 DMZ
In networking, the De-Militarized Zone (DMZ) is a part of your LAN that has been
isolated from the rest of the LAN, and opened up to the WAN. The term comes from
the military designation for a piece of territory, usually located between two opposing
forces, that is isolated from both and occupied by neither.
