You will need to create LAN interface on L3 features->Interface page.

Here is an article for other configurations, but it contains the L3 interface steps.

  @Somnus I already created a static IP interface for the LAN in L3 Features>Interface. The switch can be accessed through this interface IP but only from other devices on the LAN. I need it to also accept traffic from other subnets because the firewall allows inter communication between one of the VLANs and the LAN but the switch blocks administration access from other subnets.

Oddly, when I created another interface but this time for one of the VLANs, and it was set as DHCP, I could access the switch from my VPN and other subnets etc. As soon as I switched this VLAN's created interface to STATIC IP, the switch rejefcted all requests to access it. It only liked the DHCP on VLAN for access.

  @telcoguy I was able to connect from a different VLAN when I added a static route as follows ...

Destination - 0.0.0.0, Subnet Mask - 0.0.0.0, Next Hop - Your Default Gateway, Distance - 1

When I had the distance at 255 (I believe that was the default for these switches) I couldn't see the switch from a different VLAN.

Sorry for my ignorance, I have a similar problem, but I only have the ER605 gateway and the SG2428 switch, and I can't see the L3 layer options.

To create static route in omada?

Thanks!.
