To allow traffic from the Internet to your local network, you will need to open up ports or the router will block the request.
Because our routers use NAT (Network Address Translation), you can only open a specific port or ports to one computer at a time. For example: If you have 2 web servers on your network, you cannot open port 80 to both computers. You will need to configure 1 of the web servers to use port 81 (or any other non-80 port). Now you can open port 80 to the first computer and then open port 81 to the other computer.
Step 1: Open your web browser and type in the IP address of the router (192.168.0.1 by default)and hit Enter.
Step 2: Enter the username (admin) and password (blank by default), and then click Log In.
Step 3: Click on the Advanced tab along the top and then click on Port Forwarding on the left-hand side.
Step 4: Next to IP Address, enter the IP address of the computer, or select your computer from the drop down box and click the arrow (<<) button.
Step 5: Enter a Name for your Port Forwarding entry.
Note: The Application Name drop down menu contains a list of predefined server types. If you select one of the predefined server types, click the arrow button next to the drop down menu to fill out the corresponding field. This will also fill in the TCP Port and UDP Port. If you choose this option, skip to Step 7.
Step 6: Enter the port information under TCP Port and/or UDP Port.
Note: This feature allows you to open a range of TCP and/or UDP ports to a computer on your network. Separate multiple port entries by a comma (,) (Ex. 88,3074), and a dash (-) for a range of port entries (Ex. 1500-4999) . To open a single port using this feature, simply enter the same number in both the TCP and UDP fields.
Note: This will be the schedule of time when the Port Forwarding Rule will be active. Schedules can be defined on the Tools>Schedules page.
Step 8: Next to that, choose the Inbound Filter from the drop down menu and select a filter that controls access as needed for this rule. If you do not see the filter you need in the list of filters, go to the Advanced>Inbound Filter screen and create a new filter.
Note: The Inbound Filter option is an advanced method of controlling data received from the Internet. With this feature you can configure inbound data filtering rules that control data based on an IP address range. Inbound Filters can be used for limiting access to a server on your network to a system or group of systems.
Step 9: Click the check box to activate the entry.
Step 10: Click Save Settings at the top to save your changes.
