Gateways of VMs

[ekwb]

I am currently having trouble setting up networking on my ubuntu server. The autoconfiguration by dhcp failed during installation, so I have to statically configure my network using netplan YAML files. I have two bridges setup, vmbr0, which is used by my main node, and vmbr1, which is used by ubuntu. Here is ubuntu's yaml configuration:

network:
    version: 2
    renderer: networkd
    ethernets:
        ens18:
            dhcp4: no
            addresses: [10.0.1.101/24, ]
            gateway4: 10.0.1.1
            nameservers:
                addresses: [8.8.8.8, 8.8.4.4]

Should I configure the gateway as the node's ip, 10.0.1.100, or the node's default gateway, 10.0.1.1?

Hello from France,

No there are a difference between a vm and a node.
The node is a host that can handle many of things like vms, lxcs, and other other things....
On that node, you can build vm which is really isolated from the host.

So, you have two systems that are logically separated, and from there, you begin to understand what to set up

so what should I use as a gateway for bridged networkings...?

10.0.1.1 is the default gateway for your network?.
Then this is the gateway for your vms, if they are in that 10.0.1.0/24 net

As advid said, it's your gateway address.
Forget the node!
But, fore me you should take a care of what you're doing there...
