Two VLANs, Same Bridge and Subnet

    Hello!

    I have two separate VLANs. They work well. However, I would like them to both be in the same subnet (same DHCP range of addresses) so all devices can talk to each other and that any auto-discovery (such as Bonjour) can access each other.

    Using the GUI, I attempted to put both VLAN1 and VLAN3 on the "LAN (br0)" bridge. However, I get the following error:

    Is there any way to do this?

    The reason I need to is because I have a device that operates on two separate VLANs so it must be configured this way. Thank you.

    If you need both networks to be part of the same subnet, then just put them both on the same VLAN. If even what you suggested was possible you would be effectively putting them both in the same VLAN anyway.

    In other words, if you want devices to participate in the same network, then put them in the same network.

    Reason is because I have a access point that for the guest network on it is required to be on a separate VLAN.

    Usually you don't want guests on your guest network the ability to see/communicate with your primary network, hence the vlan isolation.

    Also, your wording makes it vague to know if you're doing this, but you don't need a lan port for each vlan you hook up from your main router to your AP. Only one port is needed, you trunk the vlans, enable port tagging, and can carry multiple vlans over one port.
