[@sunitathakur3575]

Hi Sir,
Thank you very much to share this troubleshooting video.
The first time I got this kind of troubleshooting video's which is really very helpful for beginners as well as who is having some knowledge.
I was searching for a long time only for the troubleshooting part.
you explained very well each step. Kindly make some more videos on TCP live troubleshooting, IPsec, and Palo Alto also.
Thank you so much Sir.

[@willimmos2774]

This is very helpful.Thank you!!

[@afara2000]

For someone with Checkpoint/ASA/Junos experience and new to Fortigate, this video was very helpful to get me going in my new job where everything is Fortigate and Palos. Hope you have a similar video for Palo Alto firewall. Also, it would be helpful if you could mention how to redirect verbose traffic logs for Wireshark to a file on appliance because Putty buffer may not be large enough to handle few minutes of interesting traffic. Btw, does Fortigate or Palo allow tcpdump command in shell prompt if any?
