Exam MTCNA Topic 3 Question 11 Discussion

SSH access to the router targets the router itself. Therefore, any packets destined for the router (for example, to TCP port 22) are evaluated in the input chain of the firewall.
Evaluation:
* A. output ##For packets originating from the router, not to it.
* B.#input # Correct - handles traffic destined for the router (like SSH, Winbox, etc.)
* C.#prerouting # Used for NAT and mangle operations, not filtering
* D.#forward # Used for traffic routed through the router (not for router itself) MTCNA Firewall Section - Chain Functions:
"SSH access to the router is incoming traffic. Use input chain to filter or allow it." Rene Meneses Guide - Access Protection:
"input chain is responsible for traffic to the router's IP - block/allow SSH, Winbox, etc." Terry Combs Notes - Firewall Management:
"Always use input chain for filtering incoming management protocols like SSH."
