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.
