Howto prevent access to DMZ

Is there a way to create a rule that allows control over access to my DMZ?

Internal lan is masq on internet. No masq on DMZ.
Have a rule like this:

internal -> -> any -> ALLOW

ANY is my problem. Thats give access to DMZ. How do i make a rule that only make access from internal to internet ?

Put the rules allowing access to your DMZ after the drop rule, that way they are still allowed through.

THAT DONT WORK. If ASL process a rule it don't process further down in the rules. It stops on ALLOW or DROP permission.

I need another solution. ANYONE !!!!!

You need to put your internal network allow rule below the drop rule, then place the allowed connections between your internal and DMZ rules above the drop rule. So in the end the allow any rule is last as a catch all for the internal network however the catch all going to the DMZ from Internal will cause a drop.

TANK: Like this ?

Internal -> "some rule" -> DMZ -> ALLOW
Internal -> "ANY" -> DMZ -> DROP
Internal -> "some rule" -> ANY -> ALLOW
