Would like know is ther any security concern to bring in external/public IP with out NAT to inside of the enterprise network. Is it any way more secure if we use NAT?
No. NAT is a technology designed to (among other things) *enable* communication between private and public networks. Firewalling OTOH was designed to *restrict* communication between networks. Defining appropriate firewall rules will secure a public IP address just as well as a private one.
