Zyxel USG40 + Zyxel + GS1900-24 VLAN not working

Cherukuri

Dear Gurus

I need to setup a guest access on my Wifi with VLAN

I have configured VLAN on my USG40 with DHCP Server

On the Switch, I have created VLAN and assigned the ID for port no 1,2 & 3

I will connect my Wifi Ubiquiti access points to these three ports and USG is connected to port 5

When i tagged/untagged and assing the vlan id 11 to the ports 1,2 & 3 where my access points are showing as disconnected in Ubiquiti Controller

What am i doing wrong here? please guide me

Thanks

By connecting the Ubiquiti APs to the tagged port you are putting the APs in the Vlan and therefore their management IP addresses are in that Vlan. I’m guessing your Ubiquiti controller is in a different Vlan and cannot reach the AP.

What you want to do is configure a guest SSID on the Ubiquiti AP and tag it for a particular Vlan on the AP (Configured in the Ubiquiti controller). Then set up the switch port to allow both the management Vlan (probably default of Vlan 1) and the guest Vlan traffic. Untagged packets should be tagged with the management Vlan not the guest Vlan.

Hi imaohw

Thank you very much for your help, i did exactly what you suggested and now i am not loosing the connectivity, However i am still unable to get DHCP work through VLAN. Below are the configurations i have done. May be somewhere i am missing something. Can you please go through and advise me?

Attachment 1 -> VLAN configuration on USG40

Attachment 2 -> VLAN configuration on GS1900-24 Switch

Attachment 3 -> Configuration on Ubiquiti Controller Software

Hi imaohw

Thanks for your help to resolve the connectivity issue. I have managed to get this working. I have not tagged VLAN to the port in which my Zyxel USG was connected hence i was not getting DHCP on Guest Wifi. Now all is working well.

Thank you
