I have a management bridge 'vmbr0' with IP address of 10.91.1.180/24 and default gateway 10.91.1.1. Two interfaces are bonded to this bridge.
I'm trying to create another bridge 'vmbr2' for iSCSI traffic with an IP of 10.91.16.200/24 and default gateway 10.91.16.1. Two other interfaces are bonded to this bridge as well.

When i enter the IP for the iSCSI bridge, i get a message saying Default gateway already exists on interface 'vmbr0'. Both of these subnets are on separate untagged vlans. I'm not sure why i am getting this message.

How can I get past this?
 
Hi @ajpion , welcome to the forum.

The system (Linux or Windows) allows for one default gateway. Any gateway beyond default one are not default by definition and need to be scoped for a particular subnet) destination.

If your client and storage are on the same subnet - you don't need a gateway. It is perfectly fine to have a non-routable network.
