First of all, I'm no DNS expert, keep that in mind when reading my answer 
;-)

This sounds like a split horizon setup for your DNS. If I understand you
correctly, public.abcd.com is a webserver in your LAN/DMZ but publicly
available? If so, and if the bind you inherited only answers to requests
from your LAN you can just add public.abcd.com to your zone file.

But as I mentioned before, be careful with this advice. If possible, test
this with something not in production or wait for someone with more DNS
experience than me.
