Tips
Common Questions: Disabling a Firewall
What can happen if I disable my router firewall?
With your router firewall disabled, you may be more vulnerable to online attacks. While you are one of millions of people using the internet daily, hackers look for vulnerabilities and having no router firewall leaves your network completely open. Even if it's a slim chance of happening, there is still a chance.
How do I change my router's firewall settings?
First, you'll need to access your router's settings. You can do this by finding the IP address for your router (using ipconfig or checking the manual). Then, look for firewall settings. It might be labeled Firewall or SPI Firewall . This is where you'll change your firewall settings.
Should I disable my router firewall?
Unless you have a good reason to disable your firewall, you shouldn't do it. And if you do disable it, make sure to only disable it temporarily. Avoid setting your router to Universal Plug and Play (UPnP) as this leaves your router the most vulnerable, and select a different, safer option—such as port forwarding.
