Exam MTCNA Topic 2 Question 22 Discussion

MikroTik's NAT (Network Address Translation) is part of the connection tracking mechanism. NAT rules are applied only to the first packet of a connection. Subsequent packets belonging to the same connection are automatically handled by the connection tracking module using the same translation mappings established by that first packet.
Option Analysis:
* A.#True - NAT is evaluated only on the first packet of a new connection.
* B.#False - Subsequent packets are not re-evaluated against NAT rules.
Extract from Official MTCNA Course Material - Firewall & NAT Section:
"NAT rules apply to the first packet in a connection. After that, RouterOS uses the tracked connection entry." Extract from Rene Meneses MTCNA Study Guide - NAT & Firewall Concepts:
"Once the initial packet matches a NAT rule, connection tracking applies it to the whole session." Extract from MikroTik Wiki - NAT Implementation:
"NAT is evaluated on the first packet. Other packets in the same connection follow the established NAT mapping."
