I would like to use same name from intranet AND Internet?

I host two websites that are accessable from the Internet by
podcast.example.com. They are one-to-one NAT on an internal network. On
the internal network, I would like to have the hosts type
podcast.example.com into there browser and the request go to
192.168.168.240 instead of the public IP. I have 30-50 hosts on the
network so going to everyone and modifying the host file is not really an
option.
