I'm hoping to have 3 separate VLANs for different tenants of the office and a 4th VLAN to provide a Guest access WiFi.

Anybody done similar and how do I go about configuring it?  Do i just put the two ISP routers into 'bridged mode'?  Can I run separate DHCP service on each VLAN?

Presumably I can extend the VLAN's to each SSID via the Omada GUI?

 

Any help would be very welcome.

Yes, the two ISP routers are better to be configured as bridge mode, so you can prevent double NAT issue;

Each VLAN can have their own subnet/DHCP range;

All these things can be done on Omada controller.

Thanks for the helpful response and link @Somnus 

That's good to know that I'm kind of on the right path and the VLAN and DHCP configuration looks pretty simple through Omada GUI.  In terms of the two WAN links, do I need to configure anything on the TP-Link router to allow connectivity to the web and load-balancing when 2nd link is installed?  What about the ISP routers, do they need any further changes or will 'Bridged mode' be all that's required?

Anyone able to confirm that the ER605 router will do everything I require?
