The firewall is probably your problem. Whilst you may open port 1521 on it, that only gets you as far as the Listener. The Listener than spawns a server process to run on any random port number, and it is to that server process you then have to connect to make a connection to the instance.

Likely, your firewall is blocking those random ports on which the server processes can be contacted.

You'll need to investigate CMAN (connection manager) if you want to use Oracle Net Services to drill through the firewall. Or you'll need to invest some dosh in a firewall which is Oracle-aware.
