A firewall is a security tool that can block unauthorized access based on certain rules, whether it's located on a server or a computer. It can prevent QuickBooks Point of Sale from communicating with the company's data and computer. QuickBooks can normally detect and Configure Firewall Ports and Security Settings for QuickBooks automatically if it encounters any issues with blocked connections. However, there may be times when users need to configure the firewall manually.
Several of the programs listed below will be stopped when the security application disables the QuickBooks Point of Sale utility:
- Electronic Funds Transfer: Server Manager for the Intuit Merchant Credit Card
- Database Processing: being able to connect to and record changes/transactions in the business file.
- Intuit Entitlement Service: User validation & product license
When connectivity is prevented, Point of Sale will frequently automatically configure the firewall for you. You may, however, occasionally need to manually configure your firewall. Review the relevant sections of the handbook included with the firewall program if you plan to manually setup your firewall application.
