Thank you Peter. In fact, I already installed the checkpoint in the lab envirement.
I hope I could get some configuration example, such as VPN config(Checkpoint to Checkpoint, Checkpoint to PIX, VPN client to Checkpoint), Port redirect, NAT etc.

I go through some of the pdfs in the CD (include the getting start). I cannot say no use, but just help a little bit. I hope it will give me the network diagram or scenario, and following the configuraion. It will help me to undersand.
