linux iptables SNAT

you do not have to have the ip address of a machine behind iptables set on the gateway machine before you can SNAT with the ipaddress of the machine behind the firewall. In other words you can keep your valid ip address on the machine behind the gateway and still ask your gateway to SNAT with that IP.

Visio add text to shape with yellow dot

In detail, it goes something like this:

1. Create or select a shape (duh!)

2. Open the ShapeSheet via Window > Show ShapeSheet

Go to: Insert > Section and check Controls and Text Transform (if it isn’t grayed out)

You should now see both the Controls section and the Text Transform section in the ShapeSheet.

3. In the Text Transform section, set the TxtPin cells as follows:

TxtPinX = Controls.Row_1.X

TxtPinY = Controls.Row_1.Y

4. In the drawing window, reposition the control handle to a suitable default position. The text should follow along!
