SpaceDesk is an excellent tool for turning a secondary device into an additional display for your computer. Whether you’re using a tablet, smartphone, or another PC as a second monitor, SpaceDesk enables seamless multitasking. However, sometimes the Windows Firewall blocks SpaceDesk from functioning properly, preventing the devices from connecting.
If this happens, you need to add a manual exception to the firewall for SpaceDesk. This guide will take you through the steps, explaining everything in simple, easy-to-follow language.
What Is a Firewall Exception?
Before getting into the process, let’s quickly understand what a firewall exception is. A firewall acts like a security gate, monitoring and controlling incoming and outgoing network traffic. By default, it may block apps or programs it doesn’t recognize to protect your system.
Adding an exception means you’re telling the firewall that SpaceDesk is safe, and it should allow the program to communicate through the network without restrictions.
Why Do You Need to Add an Exception for SpaceDesk?
SpaceDesk relies on network communication between your primary computer and the secondary device. If the firewall blocks SpaceDesk, it can’t establish the necessary connection. Adding an exception ensures that:
Devices Can Connect: Your tablet, phone, or second PC can communicate with the main computer.
Smooth Performance: Removing network restrictions ensures the display is smooth and responsive.
Error-Free Setup: Firewall issues often cause connection errors, which a manual exception can resolve.
How to Add a Manual Firewall Exception for SpaceDesk
Adding a firewall exception for SpaceDesk involves a few straightforward steps. Here’s how you can do it:
Step 1: Open Windows Firewall Settings
Press
Windows + Sto open the search bar.Type Windows Security and click on it.
In the Windows Security window, select Firewall & network protection from the left-hand menu.
This takes you to the main page where you can manage firewall settings.
Step 2: Access the Advanced Settings
In the Firewall & network protection window, scroll down and click Advanced settings.
A new window labeled Windows Defender Firewall with Advanced Security will open.
This advanced settings panel lets you create and manage custom firewall rules.
Step 3: Create an Inbound Rule
In the left-hand menu, select Inbound Rules.
In the right-hand panel, click New Rule... to open the Rule Wizard.
Choose Program and click Next.
Inbound rules control what incoming traffic is allowed, which is crucial for SpaceDesk to receive data from your secondary device.
Step 4: Specify the SpaceDesk Program
Select This program path and click Browse.
Navigate to the SpaceDesk installation folder (usually
C:\Program Files (x86)\SpaceDesk) and select the SpaceDesk server application (spacedeskService.exe).Click Next.
This step tells the firewall to allow traffic specifically for SpaceDesk.
Step 5: Allow the Connection
Choose Allow the connection and click Next.
Select when the rule applies (Domain, Private, and/or Public).
Private is recommended for home networks.
Public can be enabled if you use SpaceDesk on public Wi-Fi, but it’s less secure.
Click Next.
Allowing the connection ensures SpaceDesk traffic isn’t blocked.
Step 6: Name Your Rule
Give the rule a name, like SpaceDesk Exception.
Optionally, add a description to remind yourself why you created the rule.
Click Finish to save the rule.
Your inbound rule is now active, and SpaceDesk should work without issues.
Step 7: Repeat for Outbound Rules (If Necessary)
In some cases, you may also need to create an Outbound Rule to allow SpaceDesk to send data out.
In the advanced settings window, select Outbound Rules.
Follow the same steps as above, specifying the SpaceDesk program and allowing the connection.
This ensures smooth two-way communication between your devices.
Troubleshooting Common Issues
Even after adding a firewall exception, you might face issues. Here’s how to address them:
1. Check Your Network Type
Ensure your devices are connected to the same Wi-Fi network. SpaceDesk won’t work if they’re on separate networks or subnets.
2. Verify the Exception
Revisit the firewall settings to ensure the exception is correctly configured. Double-check the program path and rule conditions.
3. Restart SpaceDesk and Devices
Restart both your primary computer and the secondary device to refresh the connection.
4. Update SpaceDesk
Make sure you’re using the latest version of SpaceDesk. Outdated software can cause compatibility issues.
Benefits of Adding a Firewall Exception
Adding a manual exception for SpaceDesk isn’t just about fixing connection problems. It also offers other benefits:
Faster Setup: Once the exception is in place, SpaceDesk connects seamlessly every time.
Improved Performance: Removing firewall restrictions ensures smoother communication, reducing lag or display glitches.
Secure Access: By creating specific rules for SpaceDesk, you maintain control over what the firewall allows, keeping your system safe.
Conclusion
Manually adding a firewall exception for SpaceDesk is a simple yet essential step to ensure your devices connect smoothly. By following the steps outlined above, you can configure both inbound and outbound rules to allow SpaceDesk traffic through your firewall. Whether you’re using a tablet, phone, or another PC as an extra screen, these settings guarantee a hassle-free experience.
Remember to verify your network setup and keep your software updated for the best results. With your firewall configured, you’re ready to enjoy the full potential of SpaceDesk.
