traverse multiple vlans with a device that has no gateway

traverse multiple vlans with a device that has no gateway
I have vlan 10, 20, 30 and 40 configured on 4 switches
I have a device(let's call it "BBB") that does not have a default gateway (it's configured w/another route for remote access)
Presently I can access any device on the same vlan (it's cabled to port 2 w/vlan 10) on the same switch via BBB
The switch has a trunked port allowing all vlans, the switch also has vlans built w/an ip address 4th octet ending in 100
The default gateway points to a fortinet
But I can't access any other device in another vlan on another switch using BBB
The 4 switches are all trunked together allowing all vlans (it's inline switch A <> switch B <> switch C <> switch D)
I've replaced BBB w/a laptop configured w/a default gateway and I can ping all devices on all vlans on all switches.
but the laptop w/o a default gateway, I can only ping devices on that switch (switch A) and nowhere else
any ideas?

Re: traverse multiple vlans with a device that has no gateway
Hi @auniquename
Welcome to the community!
According your description, it's work as design.
If host want to ping same VLAN device, it's no need forwarding by gateway, just running Layer-2 forwarding(mac table-based).
If host want to ping different VLAN device, it's need forwarding by gateway, need running Layer-3 forwarding(route table-based).
So you must set default gateway for device, then it can ping both same VLAN devcie and defferent VLAN device.
Hope it helps!

Re: traverse multiple vlans with a device that has no gateway
but you're not reviewing the question well enough.
The device (BBB) already has a default gateway which points to the WAN.
Device BBB is used for remote access, and it does not have a 2nd default gateway.
again no default gateway can be configured on the LAN NIC
On device BBB connection to the LAN via switch, it can only reach devices on that switch, in that vlan.
I need to be able to ping another device on another vlan which resides on another switch.
I hope this make it a bit clearer
Device BBB <-> switch A vlan A (all devices ping) <-> switch B vlan B (unable to reach any device)

Re: traverse multiple vlans with a device that has no gateway
does the switch have intervlan routing capability?

GS752TPS does not support intervlan routing capability. You might need to check intervlan routing on your router / firewall as it is the one that handles your VLAN gateways.
Hope this helps.

Re: traverse multiple vlans with a device that has no gateway
Of course support.
You have to add the uplink port(connect between two switch) to VLANs with tagged mode, then the port will traverse these VLANs traffic.
