I need to connect a PC that has already an Internet connection via on-board LAN to a Windows domain. This domain has no Internet connection, because the data is confidential. I need to do this because I need to send some files from this domain to another place (by authorized personal only).
At this day this is made via modem, but it's too old, slow and the software that does the task isn't working on Windows 7. For my boss this is better than connect the domain to the Internet.
I need to figure out how to connect this computer to the domain network without letting non authorized users share files between the domain and the Internet.
The restrictions I have are the following:
- I cannot configure switches
- I have just one more PCIe network card
- I cannot change the OS of the Internet PC
- I cannot use any more computers
I'm thinking to put a MySQL database and disable file sharing on the internet PC, and make a system that take files from that DB and sends it trough HTTP POST requests to a PHP web service. I don't know if this could be the best way to do this.
Any idea? Recommendation? Any other way?
My original idea was to put the PCIe network card to the internet PC and connect it to the domain's switch, configure some firewall software on it and disable any other traffic than MySQL (from/to domain), design a system that does the task to receive files from domain (uploaded to MySQL db from some VBA form in the domain) and send it to the external place via HTTP POST request. I hope this give some more clues about what i'm trying to do.
