Many computers use a Firewall to block harmful programs and data from their computers. However, Firewalls are also capable of blocking certain aspects of Blackboard Learn, and may need to be configured manually to allow Blackboard Learn to operate.

If you have third-party Firewall software or have made adjustments to your home router's Firewall, check the manufacturer's documentation for allowing the ports listed below.
