I'm new to Zyxel Nebula and trying to configure VLAN, but is confused by the information in the User's Guide. My Web Configurator don't show the Swich Setup menu, where I should select port-based or 802.1Q. Is this related to the Nebula NCC cloud management solution/mode?

    Hi @Saevik,

    Welcome to Zyxel community!

    Please go to switch > switch ports to choose which port you want to set.

    Then click configuration,

    And you will see the screen like below. You can set VLAN type, PVID and allow VLANs.


    Hope it helps.

    Thanks Melen, but it seams that I have to do more homework regarding VLAN and routing as well. I don't have a Nebula NSG or a router with VLAN support and I now understand this is needed.

    The cloud mode seams to take away a lot of stand-alone mode options. I will consider to reset the switch to stand-alone mode to explore the VLAN options in the local web configurator. It seams like the VLAN options in Nebula/cloud mode is less than in stand-alone mode. 

    If I select stand-alone mode I will find a lot more guides to help with my configuration. In cloud mode it's not much to find.

    @Saevik,
    Actually, using cloud mode is much easier than you think.
    Select trunk for the port connecting to other network device, such as gateway, access point, another switch...etc.
    Select access for the port connecting to end device, such as PC, IP phone, IPTV, IP camera, printer...etc. The system will do the rest for you automatically.

    @Zyxel_Albert,
    Thanks. Are there any documentation/guides on this topic? VLAN setup in cloud mode. My router without VLAN support is connected to Port 1 (Internet/Uplink) - Trunk port with 'PVID 1', Allowed VLANs: 'all'. I want a port with VLAN2 to connect a guest Wireless AP and to get only Internet to this port. Is this possible in cloud mode?

    It sounds strange to create VLAN2 on Switch but there is no VLAN2 interface on your router...how your VLAN2 wireless clients get DHCP IP?🤔

    Hi @Saevik,
    Normally you can't configure multiple VLANs on switch if your router doesn't support VLAN. The client under VLAN 2 will not get DHCP IP and not able to access internet. 
    Here is a workaround. Keep your port 1 setting and connect another port, for example port 2, to your router. Set port 2  as Trunk port with 'PVID 2', allowed VLAN 2.  Set the port connects to guest Wireless AP as Trunk port.
    Please note that, since your router doesn't support VLAN, traffic could be forwarded cross VLANs by your router. You should find a way to isolate traffic from different LAN port on your router.

    @Zyxel_Albert,
    Thanks. I'm learning, and I understand this is not at all the normal topology. Do you mean two cables from my router? One to port 1 and one to port 2.

    "Example 3" in this guide it's what I'm aiming at:  https://www.smallnetbuilder.com/archives/lanwan/lanwan-howto/32486-how-to-segment-a-small-lan-using-tagged-vlans?start=1

    I beleve I may need to go for stand-alone mode to do it this way?

    Hi @Saevik,
    Yes, my suggestion is to connect two cables from your router to switch.

    The link you posted is not an official answer. By doing that way all the traffic from internet will flood to both PC1 and PC2. It is not real segregated. It's highly not recommended.

    @Zyxel_Albert,
    Ok. Thanks again. This is for my real small home network, and it's not so important to follow all the rules I believe. But I will try to understand what you are meaning with this flood of Internet to both VLANs. My first thought was - Yes! that's what I'm after. Internet to both VLANs. Is this bad for safety, the amount of traffic or for both? If this is real bad even for a small home network, I will consider a Zyxel Nebula NSG. I have just ordered a Zyxel Nebula NAP102 and hopefully this will play together without to much time spent on configuration.
