The last task in this lab seems to overlap with pervious ones. It seems as though the first 2 NAT commands are not needed given the 3rd one.
Task:All other traffic from VLAN 59 should be translated with the original IP address preserved.
access-list NAT_EXEMPT permit ip 136.1.59.0 255.255.255.0 host 150.1.1.1
nat (VLAN59) 0 access-list NAT_EXEMPT !
nat (VLAN59) 0 0.0.0.0 0.0.0.0
