NAT terminology focus: In Cisco NAT terminology, which address represents the external (remote) destination host after translation occurs?

Introduction / Context:
NAT terminology uses four named address types to describe how inside and outside hosts appear before and after translation. Correctly identifying these terms helps you read NAT tables and troubleshoot connectivity.

Given Data / Assumptions:

• We focus on the destination host as seen from the inside after translation.
• Standard Cisco NAT definitions apply.
• Traffic flows from inside to outside.

Concept / Approach:

Outside global is the external host’s actual, routable address as seen from the NAT device (typically a public address on the Internet). Outside local would be the external host’s address as it appears inside, if translation of the outside address is performed (less common). Inside local and inside global describe the internal client’s pre- and post-translation identities.

Step-by-Step Solution:

Verification / Alternative check:

Examine show ip nat translations: entries typically show Inside Local → Inside Global and Outside Local → Outside Global; the public remote server is represented as Outside Global.

Why Other Options Are Wrong:

Inside local/global identify the internal client pre/post translation.

Outside local is an optional translated view of the remote host inside; not the canonical external destination identity.

Common Pitfalls:

Swapping “inside” and “outside” terms; assuming “local/global” denotes private/public for both sides uniformly without regard to translation perspective.

Final Answer:

Outside global
