Look at the Address Translation tab of your rulebase. Whichever NAT rule
appears first will take precedence. If both are automatic rules, then
keep in mind that automatic static NAT rules are placed above automatic
hide NAT rules. If these are a manual NAT rules, then it all depends
where you placed the rules in relation to each other.

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,
