Why two different Reporting IPs always yield false when you apply an AND condition in Fortinet NSE 5 contexts.

If the Reporting IPs are both different, what will using an AND condition lead to?

• A. Always true
• B. Always false

Answer: (B)

When both Reporting IPs are different and an AND condition is applied, the result will always be false. This is because an AND condition in logical operations requires all conditions to be true for the overall expression to evaluate to true. In the context of Reporting IPs, if you have two distinct IPs, for example, IP1 and IP2, no single statement in relation to these two can simultaneously satisfy the condition of both being equivalent. Therefore, since one Reporting IP cannot match or confirm the state or value of the other when they are indeed different, the logical outcome with the AND condition applied turns out to be false. This concept is key in understanding logical operations within programming or filter conditions where conditions need to align in order for a valid true condition to emerge.

Two IPs, one clean rule: the truth about AND

Let me ask you this: think of two reporting IPs, each a distinct address in your network. If you’re testing a condition with an AND between them, what happens when the addresses are different? The answer is simple, but it trips people up if you’re not paying attention to the wording: always false.

That’s the essence of the boolean operator AND. In logic and in networking rules, AND means “both conditions must be true at the same time.” If you have IP1 and IP2, and IP1 ≠ IP2, you’re asking your system to confirm two things that simply cannot be true at once: “the source is IP1” and “the source is IP2.” A single packet, or a single log entry, can’t come from two different places simultaneously. So the whole expression collapses to false.

Fortinet context: Reporting IPs in day-to-day security work

In Fortinet ecosystems—whether you’re bouncing through FortiGate firewalls or aggregating data with FortiAnalyzer—you’ll encounter scenarios where IP addresses are used to filter, report, or correlate events. You might be looking at a rule that checks two reporting IP fields, or you could be filtering logs by the IPs that reported an event. In either case, the same logic applies: when the two IPs you’re comparing are different, an AND condition will not produce a true result.

Think of a real-world analogy: you’re at a check-in counter for two different guest lists. If you insist that “the guest is on List A AND List B,” and the guest is only on List A but not B, you’ll be turned away by the system. The same idea translates to IP checks: the system wants both conditions to line up perfectly at the same moment, but with two different IP addresses, that moment never happens.

A concrete example to pin it down

Suppose Reporting IP 1 is 203.0.113.10 and Reporting IP 2 is 203.0.113.20. You set a rule like:

• Condition: ReportingIP1 equals 203.0.113.10 AND ReportingIP2 equals 203.0.113.20

For any given event, it’s impossible for both parts to be true if the two IPs are genuinely different. The event would have to originate from both IPs at once, which doesn’t happen in normal network traffic. Therefore, the rule evaluates to false in every case.

Of course, if by some quirk both reporting fields point to the same address (IP1 equals IP2), then the AND condition can be true, but that’s a rare edge case in most multi-device reporting setups. When you see two different IPs, you can read the AND as a double-lock that simply won’t click into place.

Why this matters for your Fortinet toolkit

This isn’t just a nerdy curiosity. It affects how you design filters, alarms, and incident workflows. If your goal is to flag activity that involves either of two reporting devices, OR is your friend. If you want to check that both devices report a matching state, you’ll need to craft a scenario where both conditions can coexist, which often means rethinking what you’re comparing or how you’re collecting data.

Practical tips you can actually use

• Use OR when you want to catch activity from either IP: If you want to monitor traffic from IP1 or IP2, OR ensures that any match triggers the alert. This is the natural fit for most access-control or anomaly-detection rules where either IP is a valid concern.

• Use AND only when a single event must satisfy two simultaneous criteria: If you’re validating a situation where two independent conditions must hold at the same time, you’re in AND territory. But when two reporting IPs are different, the AND will almost always be false—so double-check the premise.

• Watch out for field semantics: Some Fortinet dashboards or filter builders label fields as “Reporting IP” or “Source IP.” Make sure you’re applying the operator to the intended fields. A mismatch here can lead to unexpected results, even when your intuition says “this should work.”

• Edge cases matter: If you’re testing a scenario where the same device can report from multiple paths, or if you’re linking logs that come from different devices but describe the same session, you may need to normalize or map IPs before applying AND. Normalization is a quiet hero in security data work.

• Keep it simple: Start with the simplest expression that captures your intent. If you’re unsure whether an AND will ever be true with two different IPs, test a small snippet or a lab scenario. It’ll save you debugging time later.

A quick digression on logging and reporting

In security operations, logs are more than notes; they’re evidence. FortiGate devices push logs to FortiAnalyzer or other SIEM-style collectors, and those logs carry IPs, timestamps, user IDs, and more. When you filter or join logs by multiple IP fields, the boolean algebra underneath becomes visible in a hurry. The moral: clarity about what each IP column represents—and how your rule reads those columns—will save you from chasing phantom alerts.

If you’ve ever built a cross-device correlation stroke, you’ve likely felt that exhilarating, a little dizzy, moment when two data streams finally align. The rug pull happens when you forget that an AND across two different IPs cannot be satisfied by a single event. In those moments, switching to OR or rethinking the data model brings the whole picture back into focus.

Edge-case nuance worth remembering

• If IP1 equals IP2, AND can be true: That’s the math talking. In a simple single-IP scenario where both fields are the same device reporting the same address, an AND condition might be logically satisfied. It’s not common in multi-device deployments, but it’s a heads-up worth keeping in mind so you don’t trip over a rigid assumption.

• If you want to express “the event is from either of two devices, but not both,” you’d use a combination of conditions that reflect the operational reality you’re after. Sometimes that means grouping conditions or using XOR-like logic in more advanced query languages.

A memorable mental model

Here’s a friendly way to keep it straight: think of AND as a “double-check.” For something to pass the test, both checks must say “yes.” If the two checks are about different dogs in the same park—meaning two different IPs—the double-check will always fail because both dogs aren’t in the same place at the same time. OR, in contrast, is a “one or the other” invitation—that dog A or dog B can trigger the alert.

Bringing it home for daily security work

If you’re about Fortinet NSE 5 topics, you’re likely juggling a mix of firewall rules, log filters, and reporting dashboards. The simple truth about the AND scenario with two different Reporting IPs is a gentle reminder: don’t force a match where the data cannot align. When you want to capture activity that involves either IP, switch to OR. When you’re chasing a condition that truly requires both IPs to line up, ensure your data model makes that possible, perhaps by correlating events from the same device or by enriching logs with a common field.

Here’s a quick, practical checklist you can keep handy:

• Confirm what each IP field represents in your rule or filter.

• Decide whether you want to include either IP (OR) or require both (AND).

• Test with representative samples from IP1 and IP2 to see how the rule evaluates.

• Consider data normalization if multiple devices report similar events under different IPs.

• Document the reasoning: a short note in your rule description helps teammates avoid misinterpretation.

Closing thought

Boolean logic isn’t fancy math gymnastics—it’s the backbone that keeps your security posture predictable. When both Reporting IPs are different, an AND condition simply won’t give you a true result. You’re not missing something invisible; you’re just aligning your expectations with how logic behaves in real networks. So next time you’re mapping a rule, take a breath, check the IPs, decide whether you need both or either, and let the logic do its quiet, reliable job.

If you want to keep the momentum going, bring these ideas into your next Fortinet configuration review. A small shift in how you frame a condition can save you hours of chasing after noisy alerts and give you a clearer, calmer view of your network’s heartbeat. Budding network security pros often find that mastering these little clarity moments pays off big when the next incident lands on the desk. And that’s the kind of confidence that makes the work feel not just doable, but genuinely satisfying.
