Re: Sqlnet & Firewall

Hi Johnny,

1521 (or 1526) is used only by listener when client program tries to connect. In dedicated mode (your case) new server process is forked by listener to serve client requests. And this new process uses another port (not 1521 or 1526). This is described in Net8 Administrator's Guide.
