Now, it is clear that NAT will happen first and then the encryption. ( I am
also thinking that when routing and NAT are together, NAT happens first and
then Routing).
Question is :
1.Is it Only Cisco implementation that does NAT first then Encrypt or it is
some standard.?
2. Was there a reason for them to implement like this or it is the behavior
of the IOS. ( I was also Just thinking about using NAT and IPSec for some
VoIP application- just an another problem)
Thank you every one.
Rajeev.

You are basically correct. The actual term is "encapsulating" when talking
about the packets that go over IPSec using the public address.
