HITRON BVW-3653 USER’S GUIDE
FIREWALL
±
Deny the devices on the list access to the BVW-3653 and the network (in which
case all other devices can access the network)
or
±
Allow the devices on the list to access the network (in which case no other
devices can access the network)
4.1.5
IP FILTERING
IP filtering allows you to prevent computers on the LAN from sending certain types of
data to the WAN. You can use this to prevent unwanted outgoing communications.
Specify the IP address of the computer on the LAN from which you want to prevent
communications, and specify the port range of the communications you want to
prevent. The BVW-3653 discards outgoing data packets that match the criteria you
specified.
4.1.6
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 BVW-3653 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.
4.1.7
PORT TRIGGERING
Port triggering is a means of automating port forwarding. The BVW-3653 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 BVW-3653 automatically opens the incoming ports specified in the
rule, in anticipation of incoming traffic.
4.1.8
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.
