Which steps verify that a NAT rule translates internal addresses to the internet?

• A. Inspect /ip firewall nat print and perform a LAN-to-internet test; review connection tracking for translated addresses
• B. /ip firewall nat print
• C. /ip firewall filter print
• D. /ip address print

Answer: (A)

Verifying NAT translation requires confirming both that a NAT rule exists and that it actually translates traffic as it goes to the internet. Start by inspecting the NAT rules to ensure there is a source NAT (masquerade or srcnat) rule that applies to internal addresses destined for the internet. Then generate real traffic from your LAN to the internet to observe the translation in action. Finally, check the connection tracking table to see the active session showing the internal IP being translated to the router’s internet-facing (translated) address and port. This combination proves not only that the rule exists, but that it’s actively translating internal addresses for outbound traffic. Relying on just listing NAT rules doesn’t demonstrate that translation is occurring. Checking firewall filter rules or merely listing assigned IP addresses doesn’t confirm NAT behavior either.
