Hello,
If you have 2 different outside interfaces, this is easy, using statics
static (outsideinterface1,dmzinterface) x.x.x.x y.y.y.y netmask 255.255.255.255
x.x.x.x is an ip address on the outside1 interface.
For the other interface:
static (outsideinterface2,dmzinterface) z.z.z.z y.y.y.y netmask 255.255.255.255
where z.z.z.z is an ip address on the outside2 interface.
