Hi

I am trying to setup Azure Extended Network from OnPremise to Azure using this documentation.

Extend your on-premises subnets into Azure using extended network for Azure | Microsoft Learn

I already setup VPN between OnPrem and Azure with VPN Gateway and checked connection.

I created vNet with 3 subnets in Azure 1 for VPN 1 for External Network and 1 for Extended network which overlap with my on Prem subnet 192.168.20.0/24

Windows Server 2022 Azure Edition created on Azure with Hyper-V role VMSwitches and with 2 vNIC connected to External (Main with gateway and 2nd to extended subnet without gateway)

Windows Server 2022 Datacentre deployed to On-premise with 2NIC 1 in routable subnet from which i can ping Azure Appliance and 2nd in my on Prem extended network.

I creaded 3rd server in OnPremise with W2022 and installed latest version of WAC. Logged to azure install Azure Extended Network extension and added my Network Extender onpremise server to WAC.

After setup starts it ask me to select which network to extended and this network is 192.168.20.0/24 in 2nd window i need to choose Subscription in Azure, RG, and vNet. After WAC need to automatically detect my extended subnet inside VNet but it can't detectd it and say that " Warning No subnet(192.168.20.0/24) found in current selected virtual network**"**

So what can be

WAC

vNet

    st update. WAC can't parse Azure API request. I used fiddler to view http request and can see that subnet is returning inside JSON but WAC can't parse it. MS need to update WAC extension to catch these changes inside Azure. Lost 2 week of my life.Untitled
