Configure your firewall
If you use only Windows Firewall (the Microsoft firewall that comes pre-installed with Windows) you do not need to configure it manually. AkrutoSync installer configures Windows Firewall when you install AkrutoSync.
If you have non-Microsoft firewall software (such as Symantec, ESET, etc) installed on your computer, you will need to configure it to allow AkrutoSync to use TCP ports 443, 80, and 54321. Our firewall configuration guide is available at http://www.akruto.com/firewall-configuration/. If your firewall is not listed in our firewall configuration guide, please refer to documentation from your firewall vendor.
