    Tunneling is a technique used in networking to encapsulate one type of network packet within another. It allows the transmission of packets of one protocol (such as IPv6) through a network that only supports another protocol (such as IPv4). Tunneling is often used to solve compatibility issues between networks or to securely transmit data across a public or untrusted network.

      Same here, the lesson is stuck on how the tunnel works; it is not moving to the next lesson, implementing the tunnel manually.

    These scenarios are too vaguely specified: specifically, there is no GOAL. You cannot solve a scenario: it’s just the way things are.

    I have a problem with this lesson, the completion part does not step to the next lesson and appears as if I have missed or omitted something. Any idea how to go over this as I need my points badly

    Seems I’m also unable to continue to the past the “How tunneling works” lesson as there is no “mark complete” button.

    Could now get past by closing the tab and going back to the course.

    Is there a problem with the “how tunneling works lesson” completed all the subsections but I can’t complete and move to the next lesson. Seems others had this as well, what’s the solution?

    I am stuck on “How tunneling Works”. I am done with that topic but unable to move to the next one. The video keeps looping. What is the way forward.

      I just solved mine by finishing the tunneling lesson (the page that says Exit Lesson), clicking again on the lesson on the left-hand side menu and resuming it. Then it comes back to the Exit lesson page, which then worked.

        Yes. Take your time to complete the tunnel endpoints that speaks to encapsulation and decapsulation part under examine the tunnel components in the section how tunnelling works and it will move to the next section.

    I managed to get past the stuck level.. But this was purely a trial and error. My laptop got stuck at ‘how tunneling works’, I tried with my phone, still got stuck. I repeated the entire lesson on a laptop, still didn’t work. Later, I tried with my phone and it worked. Not sure whether there is an exact solution to this. Will await in case any has an exact solution
