This article will show you how to open ports in your router firewall or Windows firewall. By default, most ports in the firewall are closed to prevent intrusion. Opening the ports can fix the problem with connecting the device to the router and the software to the device, but it will also reduce the security of the system.
Method 1 of 3: How to Open Router Firewall Ports
Step 1. Find out the IP address of the router
To open the router's settings, you need to know its IP address.
- Windows: Click Start> Settings> Network & Internet> Network Settings, and then find the IP address in the Default Gateway line.
- Mac OS X: Open the Apple menu, click System Preferences> Network> Advanced> TCP / IP, and then look for the IP address in the Router row.
Step 2. Open the router settings
Launch a web browser and enter the IP address of the router in the address bar.
Step 3. Enter your username and password
If you have already changed the settings of the router, enter the selected username and password; otherwise, enter the credentials that can be found in the instructions for the router or on the manufacturer's website.
If you forgot your username and password, reset your router
Step 4. Locate the Port Forwarding section
The modem settings interface depends on the device model. Therefore, look for this section on the following tabs:
- Port Forwarding;
- "Gaming" (Games);
- Virtual Servers;
- Protected Setup;
- You can also look under the “Advanced Settings” tab.
Step 5. Open the desired port
This process depends on the router model, but in most cases, you will need to enter the following information:
- Name (Name) or Description (Description): Enter the name of the program.
- Type (Type) or Service Type (Service Type): Select "TCP", "UDP" or "TCP / UDP". If you are not sure which type to select, click TCP / UDP or Both.
- Inbound (Input) or Start (Initial): Enter the port number. If you need to open more than one port, enter the first port number.
- Private (Private) or End (End): Enter the same port number. If you need to open more than one port, enter the last port number.
Step 6. Enter the IP address of the computer
Do this on the “Private IP” line or on the “Device IP” line. You can find the IP address on a Windows or Mac OS X computer.
Step 7. Save the settings
Click the Save or Apply button. If prompted, restart the router for the changes to take effect.
You may need to check the “Enabled” or “On” checkbox next to the line with the port number

Step 9. Enter the port range
Check the box next to Specific local ports, and then enter the port numbers you want to open. You can open multiple individual ports by separating them with a comma, or you can enter a port range using a dash between the first and last port numbers.
For example, enter 8830 to open port 8830; enter 8830, 8824 to open port 8830 and port 8824; enter 8830-8835 to open ports 8830 through 8835
