VLAN to VLAN-unaware switch

carlos_silva

Hello.

I have two acces points, with two SSID's on two different VLAN's, 1 and 2, one managed Zyxel switch, one VLAN-unaware switch, and a VLAN-aware firewall.

One of the access points connects to the VLAN-unaware switch, the other access point connects to the Zyxel switch, the Zyxel switch connects to the VLAN-unaware switch, and the VLAN-unaware switch connects to the firewall.

The VLAN's on the access point connected to the VLAN-unware switch are working without a problem. Both SSID's are working and the firewall recognizes both VLAN's and separates them.

On the access point connected to the Zyxel switch, only the default VLAN, 1, is working. When trying to connect to the second SSID with VLAN 2, the devices fail to connect to the network.

The Zyxel switch has default configurations, and I never configured a managed switch before.

What could be the problem? Can anyone help?

Thank you!

Hi @carlos_silva,

Which Zyxel-managed switch are you using? Please reference these FAQ to set up VLAN on your switch.

The VLAN setting should be tagged on the switch uplink port and the AP connecting port.

Additionally, if the traffic still does not pass after setting the VLAN, the issue might be due to the VLAN-unaware switch. Therefore, you need to change your topology to fix this issue.
