Hi Rahul,

can you try this:

dig @8.8.8.8 A corp.local
dig @8.8.8.8 A corp.local +short

Just validate before that your F5 can contact google DNS (check routing an FW rules). You can also try dig or nslookup with an internal DNS an try to resolve internal name (I suppose that fw rules was right for this).
