How to restrict Oracle to my PC vs Internet

I'm just starting to develop on Oracle. I just finished the first VB sample program that connects to the database. During that test, I noticed that several Oracle tools and services are dependent having access to the internet, even though the database is on my PC. Zone Alarm reports that the several java programs, Listener and Agent services want access to the internet, not just my trusted LAN. Since all development and testing will be on the internal LAN, I want to restrict these programs from accessing or acting as server on the internet. If I use Zonealarm to enforce this requirement, agent and listener services fail. I have to allow them access to local and remote ips or I cannot connect to the database on my own machine.

Is there a way I can be more restrictive?
