title: how to connect oracle client to virtualbox
body: <p>So i will do my best to write everything down. I have an oracle virtual box installation with windows 10 pro installed. In this instance i have my oracle db setup. This virual box is setup in a debian 10 server. I created a NAT network between them to create port forwarding. I used the standard 1521 port on both the vm and the server. I also opened 1521 port manually from the server just to be sure. The windows 10 firewall settings have been modified and 1521 port is permitted( again opened manually). When i try to ping to my server's ip it succeeds. The same happens when i ping with ip and 1521 port. Every time i try to connect with an outside oracle client installation ( on the same network ) i have the following error :
  ORA-12547: TNS:LOST CONTACT . I also have changed the tnsnames file with the appropriate information so that i can connect.</p>
  <p>Any leads on what to check next ?</p>
  <p>Thanks in advance</p>
