MS425-16 Routing Issues Firmware 9.32

I've got a MS425-16 as a Core, connected via a trunk port to a stack of three MS225-FP's.  All are running v9.32

VLAN 1, VLAN,2 VLAN3 are setup on the Core.  No VLAN's on the stack.

From VLAN 1 I can successfully ping from the tools menu.

I try the same with VLAN 2 and 3 but can't ping

However, if I leave a ping running from VLAN 1 to and then try again from VLAN 2 and 3 I get a response !

If I run MTR against an address in VLAN 1 it confirms routing is taking place on the Core.

If I do the same on VLAN 2 and 3 it reports that it's jumping to the firewall !  Why ?  All VLANS exist on the Core so surely the routing should be taking place here.

The default route is to the non-Meraki firewall.  I've confirmed all necessary routes exist on the firewall.

I've read others having issues with v9.32.  Is this a symptom ?  This is driving me mad as I can't see anything wrong in my setup.


Kind of a big deal

Are you sure your firewall is also set to NAT for VLAN2 and VLAN3?


Does your firewall attach to VLAN1?


ps. I don't think this will have anything to do with 9.32.

Thanks for getting back so quickly.


Yep, F/W attaches to VLAN 1.  I'll double check NAT for VLAN 2 and 3 and will get back, but I'm sure this is in place.
