If you want particular programs to be able to access the internet, you must add them to Allowed Programs list in the Settings window.
You can also add Allowed Services (TCP/IP ports) as well as Allowed IPs and Allowed Websites.
So if you need particular program or internet resource to be available, you can specify it in Settings. Of course you must know for sure which program, IP address and/or TCP/IP service you want to allow.
