Here's how it's done: Connect to the NetGuardian using either NGEdit, the Web Browser Interface, or the TTY interface, and navigate to Port Definition, as shown in the side figure. (The example shown is from NGEdit, but any of the NetGuardian's software configuration interfaces will do).
To disable TCP access, simply set the Port Type to Off, as shown. When set to Off, the port is no longer associated with a TCP socket, completely disabling the port from direct proxy connection.
In the screenshot, Port 1 is configured as a TCP port to connect to a device labeled EQPT 1. This device can be reached by both direct and indirect connections. Port 2 is associated with a device labeled EQPT 2, but its Port Type is set to Off.
EQPT 2 can't be accessed by a direct proxy connection, but it's still available through an indirect proxy connection, mediated by the NetGuardian and its password protection. Authorized users with the correct password can log on to the device. Users without the correct password are shut out.
