    Hi @Ricardo_ITS,

    Thanks for the tech support. I have deleted it from the public to protect privacy. I will back to you soon.

    Hi @Ricardo_ITS,

    After checking the tech support, I found the switch disconnected due to the connection expired. Could you help to take a test for clarification?

    1. Please connect a PC to the switch in the problem subnet.
    2. Open any browser and visit "http://portquiz.net:4335" and "http://portquiz.net:6667".

    In the case of port 6667, the result is the same in my network, in the client network or even in my home network, it is something that I already tried last week since I read it in a post here in this community

    Hi @Ricardo_ITS,

    Thanks for your feedback.

    Could you help to enable Zyxel support access for me to confirm the configuration between Nebula and tech support?

    Also, since you mention " it does not receive any communication from those ports.", may I know how you clarify it?

    At last, could you please help to check the below:

    1. Is there any IP conflict?
    2. Is the MTU size on the firewall 1500?
    3. Is the cloud LED steady green or steady amber?
