Port Forwarding
The Port forwarding list is used to configure the Network Address Translation (NAT) rules currently in effect on the router.
Figure 49 – Port forwarding list
The purpose of the port forwarding feature is to allow mapping of inbound requests to a specific port on the WAN IP address to a device connected on the Ethernet interface.
Adding a port forwarding rule
To create a new port forwarding rule:
1.
Click the
+Add
button. The port forwarding settings screen is displayed.
2.
Use the
Protocol
drop down list to select the type of protocol you want to use for the rule. The protocols selections available are
TCP, UDP
and
All.
3.
In the
Source IP Address
field, enter a “friendly” address that is allowed to access the router or a wildcard IP address (0.0.0.0) that allows all IP addresses to access the router.
4.
The
Source Port Range (From)
and
(To)
fields are used to specify the port(s) on the source side that are to be forwarded. This allows you to send a range of consecutive port
numbers by entering the first in the range in the
(From)
field and the last in the range in the
(To)
field. To forward a single port, enter the port in the
(From)
field and repeat it in the
(To)
field.
5.
In the
Destination network adress
field, enter the IP address of the client to which the traffic should be forwarded.
6.
The
Destination Port Range (From)
and
(To)
fields are used to specify the port(s) on the destination side that are to be forwarded. If the Source port range specifies a single port
then the destination port may be configured to any port. If the Source port range specifies a range of port numbers then the Destination port range must be the same as the Source
port range.
7.
Click the
Save
button to confirm your settings.
