Port Forwarding - NetComm NTC-220 User Manual

Port forwarding

The Port forwarding list is used to configure the Network Address Translation (NAT) rules currently in effect on the
router. To access the Port forwarding page, click on the Networking menu at the top of the screen, click on the
Routing menu on the left, then click on the Port forwarding menu item.
The purpose of the port forwarding feature is to allow mapping of inbound requests to a specific port on the WAN
IP address to any connected device.
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 Original destination 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 IP 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.
