Refer to the exhibits.


FortiGate is pushing the POST parameters shown in the exhibit to the external captive portal server The wireless client redirection fails because certificate validation occurred while loading the web page
The wireless client browser uses the FortiGate self-signed certificate to access secured web pages The SSID on FortiGate has the captive portal setting
What could cause the certification validation error on the wireless client?

The numerical IP in the POST could be the culprit too.

Wait, could it really be the POST parameters? Sounds odd.

Definitely a FQDN issue, I agree!

I think it's more about the captive portal settings.

The FortiGate uses a self-signed certificate.

I recall that if the credentials aren't embedded properly, it could lead to issues, but I’m not certain if that’s the main cause here.

I’m a bit confused about the captive portal settings. Could it really be that the FQDN type is causing the validation error?

I think the external server address needs to match the FQDN for the certificate to validate correctly. That seems familiar from our practice questions.

I remember something about certificate validation issues, but I'm not sure if it's related to the IP address format.

Ah, I think I've got it. The issue is likely related to the captive portal configuration on the FortiGate device. I'll need to carefully consider the options and choose the one that best addresses the problem described in the question.

I'm a bit confused here. The question mentions POST parameters and captive portal settings, which I'm not too familiar with. I'll need to read through the details carefully and try to understand the context before answering.

Alright, this seems straightforward. The question is asking about the cause of the certificate validation error, so I'll need to analyze the options and choose the one that best fits the scenario.

Okay, let's see. The question mentions that the wireless client is using the FortiGate self-signed certificate, so the issue might be related to that. I'll need to consider the options carefully.

Hmm, this looks like a tricky one. I'll need to carefully review the exhibits and the question to identify the potential causes of the certificate validation error.

I think both scenarios could lead to the error. We need to consider all possibilities in the exam.

That's a good point, Rory. It could also be a potential cause of the certification validation error.
RO

But what if the external server address is not the FQDN address? Could that also cause the error?
FA
Fatima

I agree with Mignon. Using a numerical IP address might not match the certificate, causing validation error.

Wait, wait, wait... did someone forget to update the FortiGate's self-signed certificate? That would definitely cause some issues with the wireless client. Time to call the IT guy, or maybe the IT hamster, if they have one.

I think the certification validation error could be caused by using a numerical IP address for the FortiGate IP.
AL

Hold up, are we sure the credentials are being passed correctly? That could definitely cause a certificate validation error. I'd double-check that the captive portal parameters are set up properly.

Hmm, I'm not sure. The external server address could be the problem, but it's also possible that the captive portal settings are not configured correctly. Maybe the FQDN option is the way to go?
MA
Maryann

I think the issue is that the FortiGate is using a numerical IP address in the POST parameters. The captive portal server is probably expecting an FQDN address, which would allow proper certificate validation.
