if you have done it, please advise the steps.

No you cannot. Sometimes you can get away with making a static ARP entry, and it'll work. But it's not guaranteed to work.

Static reservation NO > As pointed out above dont consider static ARP entries - sometimes it will work sometimes it wont!

You can set the ASA up as a DHCP Relay now.
