Configuring Port Forwarding
Port forwarding is used to redirect traffic from the Internet from one port on the
WAN to another port on the LAN. The port forwarding rules menu allows selection
of a service. Common services are available or you can define a custom service
and associated ports to forward.
The Port Forwarding Rules table lists all the available port forwarding rules for this
device and allows you to configure port forwarding rules. The table contains the
following information:
•
Status
—A port forwarding rule can be disabled if not in use and enabled
when needed. The port forwarding rule is disabled if the status is disabled
and it is enabled if the status is enabled. Disabling a port forwarding rule
does not delete the configuration.
•
Service
—Service for which this port forwarding rule is applicable.
•
Action
—Whether to block or allow traffic (always or by schedule) that
meets these filter rules, and when the rule is applicable.
•
Source Users
—The source IP for this port forwarding rule (Any, Single,
Range, or Host name).
•
Local Server
—The DNAT IP address, if traffic that meets this filter rule is
sent to a local server.
•
Internet Destination
—Which of the WAN ports (if more than one is available)
that is the Internet destination for traffic covered by this port forwarding
rule.
