It is referred to as Domain based NAT and Nat Virtual Interface, (referred to in the order you listed below).
with Domain based NAT any rule I do for NAT is going to be applied only when and always when I go from an inside to outside interface or vice versa with NVI I can do rules where I NAT sometimes from interface A to B and others I NAT from interface A C. Any interface can act as a source or destination NAT. Regards, Tyson Scott - CCIE #13513 R&S, Security, and SP Managing Partner / Sr. Instructor - IPexpert, Inc.

Can any one help to understand what is difference between ip nat enable and ip nat inside/outside command Example:--1 int fa0/0 ip nat inside int s0/0/0 ip nat out ------------- example--2 int fa0/0 ip nat enable int s0/0/0 ip nat enable I know ip nat enable is new method of doing nat and create an NVI interface but my questions is, both commands are same ? can we use vice-versa or there there some situation where you can use only specific one ( I mean ipnat enable or ip natinside/outside) Thanks Nilesh _______________________________________________ For more information regarding industry leading CCIE Lab training, please visit www.ipexpert.com _______________________________________________ For more information regarding industry leading CCIE Lab training, please visit www.ipexpert.com
