Error creating new bridge - duplicate GW, but it is not

[hachiman]

Hello,
I am quite new to proxmox and try to setup my first VLAN network across a cluster of two nodes.

Right now I have, per node, one bridge, untagged, on a LACP bond of two NICs.

The network is 10.0.1.0/24, with a GW of 10.0.1.1

Now I want to create a new network for my VMs, based on .1q VLANs. The switch is capable of sending untagged and tagged pakets.

Therefore I want to create a new vmbr on each node before I can create the zone in the SDN.
I try to create a new bridge with a different subnet, 10.0.10.0/24, with a GW of 10.0.10.1
However when I try to create it I always receive an error that the gateway already exists - which it does not.

Is there something I am doing wrong or somethig I missed in my understanding of proxmox networking?

Thank you!

PS: This also happens with an entirely different network like 192.168.1.0/24

Hi,

The network is 10.0.1.0/24, with a GW of 10.0.1.1

The error message is correct, you can never have two gateways on a system, per definition. This is not something Proxmox-specific and applies everywhere.

In your case you probably just want route 10.0.1.0/24 via the new bridge. The appropriate route entry is created automatically for that subnet when you create the bridge.

Also, you want to connect both bridges to the same bond? That's not possible, there can only ever be one (parent) bridge per physical interface.
