You could connect the 3002 hardware client in two ways, one is in parallel with your Checkpoint, wherein the public interface would be on the same subnet as the outside interface of the checkpoint, hence would be on a switch port that would be on the same vlan as the outside interface of checkpoint, and the inside interface would be on the same subnet as the checkpoint inside interface. Then you could follow the sample config.
Another way is to place the inside interface on the same subnet as the inside interface of the checkpoint, and then the inside interface of the 3002 would be on a different inside ip subnet. There would be pros and cons between the two but it boils down to your security policy and if you consider IPSec traffic secure enough not to do more filtering.
