You can do the following:

1. change the ip address of the involved conflicting ip network.

2. increase the global ip pool that is provided by ISP, for the first workaround that I've provided to work.

3. for the nat policy, you need to have both ends of the tunnel to nat for it to work, instead of the concentrator you should have either pix or router to nat at the other end.

4. if you have to vpn 3000 concentrator server (not c3002), then link below is appropriate for you:
