Port Forwarding
The Port forwarding list is used to configure the Network Address Translation (NAT) rules currently in effect on the router.
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 address 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.
