I can't find a reason for this to not work - Meraki MX84 - Just do your job

Right now I have the following config.

ISP Fiber < Meraki MX84 (10.30.50.5) < Barracuda web filter gateway (10.30.50.1) < 10.30.x.x subnets

I'm looking to simply remove the Barracuda web filter so that the MX84 can take over as the gateway device for the entire network. Now I would think that all I need to do is change the MX84 IP address from 10.30.50.5 to 10.30.50.1 and connect it directly to the switching network and disconnect the Barracuda.

This is what the new config looks like

ISP Fiber < Meraki MX84 (10.30.50.1) < 10.30.x.x subnets

Since all devices on the network are configured with a default gateway of 10.30.50.1 this MX84 should just pick right up but that's not the case.

When I swap all of this out and connect to my network I can't ping the MX84 at It's new IP 10.30.50.1 and I can see that it does, in fact, have the new LAN IP address from the Meraki cloud side. Is there something else I need to chance on the MX84 side to allow this device to take over as the default gateway? Meraki support is riddled with support reps that speak 15% English which makes it very difficult to troubleshoot with them.

Any ideas?
