Wait, I thought it was B? The key needs to come from the right interface.

A is correct! Only requests from the configured NAS IP are accepted.

I'm leaning towards option B as well. Creating a new NAT rule with the translation type set to None seems like the most straightforward way to exempt the flow from the default NAT rule.

This seems like a straightforward question. I'd go with option B - writing the program charter, including the mission statement and stakeholder engagement plan. That seems like the logical first step to get formal sponsor approval.

Ah, I've seen questions like this before. The key is to identify the correct network statement that matches the interface IP address on R2. I think I've got this one.
