If the application gateway backend pool contains an internally resolvable FQDN or a private IP address, the application gateway routes the request to the backend server by using its instance private IP addresses. Make sure the FQDN in the backend pool can be resolved internally.
You can verify the following configuration, it works on my side. I am using the Standard V2 SKU application gateway. The application gateway and container group were deployed into the same VNet but different subnets with no firewall rules. I use <a href="https://learn.microsoft.com/en-us/azure/container-instances/container-instances-vnet#example" rel="nofollow noreferrer">this example</a> for deploying ACI.

I have an application gateway with frontend public IP address, connected to a VNET via its subnet and using a single backend pool that points to a container group in the same VNET but different subnet.
The backend pool points to the IP address of the container group. That works!
But I don't want to rely on an IP address that could change anytime with the container restart. I already use a private DNS zone linked to the VNET. The container group is accessible as &quot;mycontainer.my-azure.com&quot; from the VNET thanks to the A record in my private DNS zone.
But putting &quot;mycontainer.my-azure.com&quot; as the FQDN of the backend pool does not work. It works with the IP address &quot;172.22.44.5&quot; but &quot;mycontainer.my-azure.com&quot; does not resolve, backend health shows &quot;Unknown&quot;. I tried restarting the APP GW from AZ CLI to no avail.
Does anyone know how to make APP GW use the VNET's private DNS zone in its backend pool?

我有一个具有前端公共IP地址的应用程序网关，通过它的子网连接到VNET，并且使用单个后端池，它指向同一个VNET中的容器组，但指向不同的子网。后端池指向容器组的IP地址。起作用了！但是我不想依赖于一个IP地址，这个IP地址可能在容器重新启动后随时改变。我已经使用了一个连接到VNET的专用DNS区域。容器组可以从VNET访问为“mycuer.my-azure.com”，这要归功于我的专用DNS专区中
