Abstract

A licensing system using a firewall gateway for protecting and licensing computers is disclosed. A firewall gateway for separating a protected computer on a private network from a public network is provided. The protected computer has a client software application residing thereon that is licensed. A client module is provided that is associated with the client software application. A proxy agent is provided that is maintained by the firewall gateway. The proxy agent is configured to validate a license for the client software application.

Claims

1. A licensing system using a firewall gateway for protecting and licensing computers comprising:

a firewall gateway separating a protected computer on a private network from traffic on a public IP-compliant network;

the protected computer having a client software application residing thereon and a client module associated with the client software application; and

a proxy agent maintained by the firewall gateway for validating a license for said client software application on said protected computer.

2. The licensing system of claim 1, wherein said proxy agent receives a license inquiry request from said protected computer, and forwards the request to a license server over an IP-compliant network.

3. The licensing system of claim 2, wherein said proxy agent receives a license inquiry response message from the license server, and forwards the response message to said protected computer.

4. The licensing system of claim 3, wherein said proxy agent periodically performs an audit of license information regarding said client application and stores said information in a cache.

5. The licensing system of claim 3, wherein said proxy agent is the only IP address visible outside of said firewall.
