A firewall acts like a wall for your computer, so it will check incoming and outgoing connections and packets. It can block malicious or suspicious traffic based on different rules. Windows includes one, but is quite basic. Firewalls are excellent for an initial line of defense in safeguarding your computer from future infections. There are lots of personal firewalls out there which work quite well for desktop computers, but all of them fall short for server usage.
It will block or allow lots of traffic automatically, but sometimes you might observe a message asking you if you would like to permit a program to connect to internet. You may temporarily switch off the Windows Firewall to see whether it’s causing the issue.
It is possible to block the programs that you do not wish to initiate outgoing connections.
