Re: hw/sw for setting up oracle db on internet

You will want to ensure that your consultants have fixed IP addresses at their end of the system so that you can use the protocol.ora file to set 'tcp.invited_nodes' so stop attacks on your database.

You may also want to put the listener onto a non-standard port (1521, 1526, and 1527 are commonly used).
