A firewall is a physical device or security software which is designed to prevent unauthorized access or connectivity network based upon a certain standard. Whether the firewall is on server or workstation it can block communication between QuickBooks POS company data and workstation.

In this article, you will get to learn about QuickBooks Point of Sale firewall settings, network configuration, POS Executable Files and their required port numbers, download, setup & configuration.

Most of the time QuickBooks Point of Sale automatically configures the ports of firewalls for you whenever the connectivity is blocked. However, sometimes we need to configure manually which we will discuss further.

If you configure your firewall application manually, you should review the appropriate sections of the manual that has supplied with the firewall program.

Some QuickBooks POS functions that will be interrupted due to Firewall

Electronic Funds Transfer: Processing of : Processing of Intuit Merchant Services credit card. Database Server Manager: It is the ability to connect and record transactions/changes to the company file(Server installation only). Intuit Entitlement Service: Product license and user validation.

QuickBooks POS Firewall Configuration Setup Manually

You need to ensure some points described below:

You should have rights to Windows Administrator rights to perform. Ensure that you have added the Firewall Ports and Executable files that QuickBooks Point of Sale requires if you are using a third-party security program. Contact the developer of your third-party security program

Now, follow the steps mentioned below to configure manually:

Open the Control Panel. Choose the Windows Firewall. Choose the Advanced Settings and click on Inbound. Click on New Rule. Choose the Port and click Next. Type the port numbers and click Next (you can check the section below for the Point of Sale Firewall Ports). Click on the Allow Connection and click Next. Enter the firewall rule name. Click on Finish. Follow the steps from 5 to 9 for the Outbound Rule.

You will get a question during manual configuration of QuickBooks firewall i.e. “What do you want to do?” with several options such as deny, block, grant, permit, or something similar options. You should choose to allow, grant or permit the action.

Permitting one action for a file does not automatically enable all actions in the Point of Sale program. Several different files perform actions that a firewall may see as an attempt to connect to the Internet connection. There must be a separate grant of permission for each action.
