Inter-VLAN traffic not working despite forwarding being enabled

[CPAudioVisual]

I have a network with (4) VLANs that need to not see each others broadcast traffic, but still be able to exchange packets for network control purposes.

I've got IPforwarding enabled on all (4) VLANs, and all ports are set as untagged, but am unable to ping across VLANs.

I thought we had things configured properly based on this knowledgebase article, but apparently not:

Any quick gotcha type things that I might have missed?

Hello,

Could you share the "show config vlan" output from the switch?
Are you able to ping the switch IP from the end device?
