Broadcast packets not passed?

[bcw]

Hello,
We have two internet sources connected to our Netonix switch with two gateways on separate subnets. If both subnets are connected the ARP broadcast from x.y.z.85 are not returned.
If I disconnect one of the gateways everything is well.
Did I make a mistake in the configuration?

What, this makes no sense? The switch is a Layer 2 device not a Layer 3 device.

Are you assigning multiple IPs to the switch via the VLANs? This is not what they are for.

The IP address on the Device/Configuration TAB is the switch address.

The addresses you can set on VLANs is a non routable IP that is meant to allow the switch to direct ping a device such as a radio that is not in the same subnet of the switch for the watchdog features.

Perhaps I was not clear.
I am not talking about the switch's IP address.
The IP addresses shown are those of the gateways somewhere else.

The system on port 3 issues the (level 2) ARP request:
00:0e:c4:d2:46:39 > ff:ff:ff:ff:ff:ff, ethertype ARP (0x0806), length 42: Request who-has 213.190.73.85 tell 213.190.73.86, length 28

There is no reply on these messages, so one option is that they are not passed by the switch

So - the question is -
With the above configuration - if an untagged broadcast packet with src MAC 00:0e:c4:d2:46:39 arrives on port 3, I expect it to go to port 5 untagged, and to port 1 tagged with the default vlan.
Is this understanding correct?

Anybody have any insights in why the switch would not send the broadcast to all connected ports?
