Difficulty: Easy
Correct Answer: Inside global
Explanation:
Introduction / Context:
Correctly identifying NAT address roles prevents configuration mistakes and speeds troubleshooting. For inside-to-outside sessions, the inside host is represented on the public side by a translated address.
Given Data / Assumptions:
Concept / Approach:
Inside global is the translated, globally routable address that represents the inside host to the outside world. Inside local is the private, pre-translation address. Outside local/global describe the destination host as seen inside or globally.
Step-by-Step Solution:
Verification / Alternative check:
Run 'show ip nat translations' and note the 'inside global' column showing the public address bound to the inside host.
Why Other Options Are Wrong:
Inside local: Pre-translation. Outside local/global: Terms for the destination host, not the source inside host.
Common Pitfalls:
Assuming “global” always equals public Internet. It indicates the address visible outside the NAT boundary, which is typically public, but could be another routed domain.
Final Answer:
Inside global
