Hi everyone,
Trying to deploy the 23h2 cluster from Azure I encounter this error
Arc server nodes must contain only one default gateway on physical network adapters.
I checked every physical server card but they all have the same gateway
The nics are made up like this
6 or 10 GB
6 static IP addresses
I also tried using DHCP to assign IP addresses but no changes.
This configuration for all Nic

Hi,
The error you are seeing means setup has detected that more than one physical adapter has a default gateway configured. Default gateways are a global configuration even though they are configured on individual adapters, so you should never have more than one default gateway configured across all adapters.
To resolve this issue, ensure that only one adapter (typically the management adapter) has a default gateway assigned.
Hope this helps!
I'm afraid it's a bug in the 23h2 release. Let's hope a fix comes out soon.
SO i was able to get around this, I had DHCP enabled on the network, i disabled that and set 1 NIC only up statically on each server. I went throught the process again and servers verified without showing this error.. I would suggest you try that, once the intent are setup i think the new IPs will be assigned accordingly.
Thank you BradN.
I will try disabling dhcp completely. Absurd anyway

I also received a similar error message while deploying 23H2 Cluster via Azure Portal.
Later I removed multiple Gatways and tried validation again.
It resolved my issue.
