I'm trying to allow access from the inside network to the DMZ temporarily. Below are my three interfaces.
nameif ethernet0 outside security0
nameif ethernet1 inside security100
nameif ethernet2 intf2 security10
ip address outside 65.12.13.14 255.255.255.0
ip address inside 10.4.1.1 255.255.255.0
ip address intf2 192.1.1.1 255.255.255.0
access-list nonat1 permit ip 10.4.1.0 255.255.255.0 172.16.1.0 255.255.255.0
access-list nonat1 permit ip 10.4.2.0 255.255.255.0 172.16.1.0 255.255.255.0
access-list nonat1 permit ip 10.4.1.0 255.255.255.0 10.10.10.0 255.255.255.0
access-list nonat1 permit ip 10.4.2.0 255.255.255.0 10.10.10.0 255.255.255.0

access-list nonat1 permit ip 10.4.1.0 255.255.255.0 10.4.4.0 255.255.255.0
access-list nonat1 permit ip 10.4.2.0 255.255.255.0 10.4.5.0 255.255.255.0
access-list nonat1 permit ip 10.4.1.0 255.255.255.0 10.4.5.0 255.255.255.0
access-list nonat1 permit ip 10.1.200.0 255.255.254.0 172.16.1.0 255.255.255.0
access-list nonat1 permit ip 10.4.1.0 255.255.255.0 10.1.200.0 255.255.254.0

access-list nonat1 permit ip 192.1.1.0 255.255.255.0 10.4.1.0 255.255.255.0
access-list intf2_out deny ip any 10.4.2.0 255.255.255.0
access-list intf2_out permit ip any any
You may want to try the following command
no nat-control
Else, you will need an access list to allow the inside network access the dmz network.
access-list inf2_in permit ip 10.4.1.0 255.255.255.0 192.1.1.0 255.255.255.0
access-group intf2 in interface intf2
