We have a stack of Catalyst 3750 switches setup as an MDF. This stack is also the default gateway for all internal networks. The issue I'm running into is that when traffic reaches our firewall (or any other device), it shows up using the MAC address...

I'm having an issue with routing I can't seem to figure out. We have a Cisco 3850 switch stack that operates at the gateway for all devices on our network. The 3850 then routes traffic to our firewall (10.51.5.1) before going out to the internet. We'...

OK, thanks for confirming. Like I said, I've never had a switch act as the gateway like this before, so this setup is new for me.

It is L3 with multiple VLANs. The MDF/switch acts as the default gateway for every VLAN we have, so it has an interface on each. We then have a static route that sends any traffic on those VLANs to our firewall and then out to the internet. So for ex...

The 10.51.0.0/16 does have the same hop as the default route right now, but that's kind of the issue, I don't want it to. I basically want anything from a 10.51.0.0/16 network going to our new firewalls and anything not on those going to the default ...

I guess what I don't understand is that we have two other static routes (10.99.0.0/16 and 192.168.20.0/24) that are going to the new firewall. Those work perfectly fine and the traffic is going where it's supposed to. So why would those work normally...

OK, that makes sense. My thought was that the 10.51.0.0/16 route would take precedent over the 0.0.0.0 route as long as you were on that 10.51.0.0 network, but it doesn't sound like that's the case. I think you're right in saying it's not doing anyth...
