Subject: does checkpoint actually do a NAT

HI All,
     I have a basic query on Firewall NAT.When I configure my checkpoint firewall to do static NAT I have to configure the firewall to accept packets in a arp proxying mode.And I am asked to put a route to the particular public IP saying that to go to the particuar NATed public IP go to the private IP in the LAN.
If checkpoint was actually doing a NAT according to RFCs like cisco does these entries would not have been necessary.So does checkpoint NAT actaully change the IP headers ? If yes why should I add a static route to the public machine ?.How does the NAT actually work in checkpoint?
Pls enlighten me with your valuable arguments.
regards,
Jayasankar
