4Select another expression that you will use to form a new logical expression in combination with the first.

5Using the radio buttons, select the type of expression you wish to construct, in this example an AND expression.

The AND expression lets you construct a logical expression where both conditions must be met for the TunnelGuard checks to pass. The OR expression lets you construct an expression where either of the conditions must be met for the TunnelGuard checks to pass. The NOT operand lets you construct an expression where the condition must not be met for the TunnelGuard checks to pass, for example the file or files in the software definition must not be found on the client machine.

6Click the Form TunnelGuard Rule Expression button.

A new expression is created and copied to the Available Expressions area (see Figure 88 on page 336).
