Depends on  the version of Checkpoint:
4.1 
Outbound: firewall nats first , policy second, routing third
Inbound: policy first, nats second, routing third. 
The natted to ip always need to be in the policy.

NG
Always nats first , policy second, routing third.

Subject: MIP's and HIDE on checkpoint NG


Would anyone know the order of operations for NAT on a CheckPoint box? The
dilemma is as follows: There exists a MIP 192.168.1.1:206.218.1.1 ->
10.1.1.1 There also exists a Hide rule: 192.168.0.0->10.1.1.1 (*hide behind
206.218.10.1*)

Does the MIP take predecedance over the hide?
So basically if 192.168.1.1 initiates a session to 10.1.1.1, will it take
the 206.218.1.1 address and not the HIDE address of 206.218.10.1?


Any information is appreciated.
Thank you,
