Model: ER605 (TL-R605)  
Hardware Version: V1
Firmware Version: 1.2.3

I have a ER605 V1 and running firmware 1.2.3 and Omada SDN 5.9.31.

 

In the OMADA controller, I set the fixed IP address of the client to 192.168.20.89 (on VLAN20), but it will always connects to 192.168.0.105 (on the base LAN - VLAN1).  If I set the reservation to 192.168.0.88 (on the base network (VLAN1) it works. Does not make a difference if I use a wired or Wi-Fi connection (I'm using UniFi APs). I've tried on different clients - same problem. I set a static IP address on the client to 192.168.20.89 and it does not connect.

 

Here are the details of VLAN20:

 

Gateway IP 192.168.20.1
Network Broadcast IP 192.168.20.255
Network IP Count
254
Network IP Range
192.168.20.1 - 192.168.20.254
Network Subnet Mask
 
255.255.255.0

Hello @RADEB 

 

Is there a switch connected between the ER605 and the UniFi APs?

Did you configure VLAN20 on your SSID from your UniFi APs?

 

If your network topology is like ER605 ---- (Port 1) Switch (Port 2) ---- AP )))((( SSID vlan20

Please ensure that the Port1 and Port2 of the Switch is configured with VLAN20 trunk ports. And the SSID from the AP has VLAN enabled and configured with VLAN20. Otherwise, the clients connected to the SSID won't get the IP address from VLAN20.

  @Fae I have a TP-Link POE Switch (TL-SG105TP) that the UniFi Aps are connect to, but I want to focus on the wired connections.

 

I want to be able to connect a particular device to anywhere on the network and the device will be assigned a fixed IP address on VLAN20 (192.168.20.XXX). Apart from the switch mentioned above which is only for Wi-Fi, the rest of the network is connected directly to the router.

All devices work in the VLAN1 network by default. If you want a device to be assigned with an IP address on VLAN20, please ensure that the device belongs to the VLAN20 network. For your case, you may need to specify the VLAN config on the ports. However, currently it doesn't support to specify the Port PVID on the ER605 router when it's managed by Omada Controller. 

 

If you want all devices to work in VLAN20 instead, that is, to replace the VLAN1 with the VLAN20, you may forget the ER605 from your Controller, and configure the Network in Standalone web UI. Go to Network > VLAN > Ports to configure the PVID to 20 for a spare LAN port, then modify the default VLAN1 network to VLAN20 (192.168.20.xxx), and connect to the spare LAN port to access the web UI again, finally configure the PVID of other LAN ports to 20. After that all LAN devices will work in VLAN20.

  @Fae Thanks for your message. How can I get a specific device, if it connects anywhere on the network, to be assigned a specific IP address on VLAN 20 without using port based VLANs?
