Objective
The objective of this article is to explain the port forwarding on the RV120W and RV220W Network Security Firewall. IP Addresses are divided into ports, so that one IP address can be used by multiple programs to send and receive data at the same time. Port forwarding is used to redirect traffic from the Internet from one port on the WAN to another port on the LAN. Any PC whose port is being forwarded must have its DHCP client function disabled and must have a new static IP address assigned to it because its IP address may change when using the DHCP function.
Note: A maximum of 100 port forwarding rules can be created.
Applicable Devices
- RV220W
- RV120W
Steps to View Port Forwarding Rule Table
Step 1. Use the web configuration utility to choose Firewall > Port Forwarding. The Port Forwarding page opens.
Step 2. The Port Forwarding Rule Table lists all the available port forwarding rules. The port forwarding rule table contains the following information.
- Action — Represents whether to allow/block traffic always or based on the schedule made when the rule is applicable.
- Service — Represents the name of the service for which the port forwarding is applicable.
- Status — Represents whether the port forwarding rule is enabled or disabled.
- Source IP Address — Represents the source IP address from which the traffic is forwarded. The options are Any, Single address and address range.
- Destination IP Address — Represents the destination IP address of the server to which traffic is forwarded.
- Forward from Port — Represents the port from which the traffic is forwarded.
- Forward to Port — Represents the Port to which traffic is forwarded.
Step 3. Click Add to add a new port forwarding rule, or check the respective check box and click Edit, Delete, Enable, or Disable to perform the respective action to an existing rule.
Note: When you click on the Add or Edit button the Add/Edit Port Forwarding Configuration page opens.
Step 4. Choose the action from the Action drop down list. The options are as below.
- Always Allow — Always allow the selected type of traffic.
- Always Block — Always block the selected type of traffic.
- Block By Schedule — Block the selected type of traffic based on the time schedule made on configure schedules.
- Allow By Schedule — Allow the selected type of traffic based on the time schedule made on the configure schedules.
Note: For Always Allow and Always Block options Schedule drop down list and Configure Schedules button are disabled.
Note: For Block By Schedule and Allow By Schedule you need to choose a schedule from the Schedule drop down list. Click Configure Schedules to configure new schedules for port forwarding. Schedules can also be configured if you choose Firewall > Advance Settings > Schedules.
Step 5. Choose the service from the Service drop down list. If the required service is not found in the Service drop down list, then click Configure Services or choose Firewall > Advanced Settings > Schedules.
Step 6. Choose source IP option from the Source IP drop down list. The source IP drop down list contains three options.
- Any — It can be any source IP address. In this case there is no need to specify start IP address and finish IP address.
- Single Address — In single address you need to specify only the start IP address for which the port forward rule is applied.
- Address Range — In address range specify both the start address and the finish address. This specifies the range of address for which the port forward rule applies.
Step 7. Enter the destination IP in the Destination IP field.
Step 8. Choose the port from which the traffic is to be forward from Forward from Port drop down list. There are two options.
- Same as incoming port — Represents that both the forwarding and the receiving ports are the same.
- Specify Port — Specify the port from which traffic is to be forwarded. Port number can be specified in the Port Number field. The port number range is from 0 to 65535.
- Same as incoming port — Represents that both the forwarding and the receiving ports are the same.
- Specify Port — Specify port to which traffic is to be forwarded. Port number can be specified in the Port Number field. The port number range is from 0 to 65535.
Step 9. Choose the port to which the traffic is to be forwarded from Forward to Port drop down list. There are two options.
Step 10. Click Save to save the settings.
