[All NSE7_NST-7.2 Questions]

Refer to the exhibit. which contains the output of diagnose vpn tunnel list.

Which command will capture ESP traffic for the VPN named DialUp_0?

Adiagnose sniffer packet any 'host 10.0.10.10'

Bdiagnose sniffer packet any 'ip proto 50'

Cdiagnose sniffer packet any 'esp and host 10*200.3.2'

Ddiagnose sniffer packet any 'port 4500'

Show Suggested Answer

Suggested Answer: C

Capturing ESP Traffic:

ESP (Encapsulating Security Payload) traffic is associated with IPsec and is identified by the protocol number 50. To capture ESP traffic, you need to filter packets based on this protocol.

In this specific case, you also need to filter for the host associated with the VPN tunnel, which is 10.200.3.2 as indicated in the exhibit.

Sniffer Command:

The correct command to capture ESP traffic for the VPN named DialUp_0 is:

diagnose sniffer packet any 'esp and host 10.200.3.2'

This command ensures that only ESP packets to and from the specified host are captured, providing a focused and relevant data set for troubleshooting.

Interesting to see that you're all wrong. Aren't you forgetting that when NATT is used, ESP is being encapsulated into UDP port 4500. If the NATT mode was none it would have been disabled which would make Option C the correct answer. However from the output we can see that the NATT mode is silent, which means NATT is being forced. Hence option D is the correct answer. https://community.fortinet.com/t5/FortiGate/Technical-Tip-IPSec-VPN-nattraversal/ta-p/197873

Option B is the way to go, folks. I mean, come on, who doesn't know the ESP protocol number by heart? Definitely not me. *winks*

I'm going with Option C. The 'esp and host' syntax looks more specific than just the protocol in Option B. Plus, the wildcard could be a sneaky way to catch the VPN IP address.

I'm not sure, but Option D might also work since it targets a specific port.

I agree with you, Option C seems like the best choice. The wildcard could be useful in this case.

Let's go with Option C then. It seems like the most precise command to capture ESP traffic for the VPN.

Ha! Option D is just a wild guess. Who would use port 4500 for a VPN? Clearly, the answer is B, unless the exam writer is trying to trick us.

Hmm, I'm not sure. Option C seems to have the right protocol and IP address, but the wildcard is a bit sketchy. Might be better to go with the direct IP address in Option A.

Option B looks good to me. The ESP protocol is 50, so that should capture the VPN traffic.
