We have an application that uses a virtual network to extend our on-premises network into Azure. We plan to deploy the application as a cloud service.

Detached Nic -> Public Static IP lost

Hi,

We have noticed during some testing that if we have a Nic that is not attached to a VM the public IP address that is associated to (set to static) eventually gets removed/cleared. Can you confirm if this is an expected behavour and if so what is the timeframe associated with it being removed/cleared? Does this also occur if the public IP address is dissociated for a period of time?

Which method is preferred during a backup/restore:

1. Swap the NICs between VM's (by detaching/attaching which keeps both the local and public configuration)

OR

2. Dissociate/associate the public IP address and change the local IP (which is set to static on the original VM) to suit.

Hello,

    We use Azure Classic Virtual Network. We have site-site VPN tunnel between Azure and Local site. I  want add additional site-site VPN connection to exist Azure Gateway. I can create Site-Site connection but I can not get configuration file for my Cisco ISR device. I know where I can found config file in old Classic Azure portal but Classic portal unavailable for me. In new portal I do not see that possibility. In new portal I get config only for Microsoft RRAS server. Gateway routing type - Dynamic routing.

Where I can get config file for second Site-Site VPN connection for classic virtual network?

Thank You.

Hi,

As per image (source) we already have VPN connections between East US and on-premise Site 2 and Site 3.

The question would I be able to reach West US and East Japan from On-premise Sites only by adding VNet-to-VNet connections between East US and West Us and East Japan without changing On-Premise routers? 

Or should network admin on-premise site routers also add additional routes to West US and East Japan?

Many thanks

Is it possible to access azure files from my local network which is connected to my azure virtual network via site to site vpn. I can access my VM's fine over the VPN, but I can't find any way to get access to azure files - seems to only be accessible from within the virtual network.

Accessing a File Share via VPN

I have setup a VM and a storage account. I am using an Azure VPN to tunnel through the ATT U-Verse firewall which blocks the 445 port which allows me to use Windows Explorer to the VM shared folders.

I would like to use the VPN to contact my Storage Account's file share.  My goal is to dump the VM and use the VPN-to-Fileshare link only.

I am able to find the private IP for the machine, thus I can connect.  However, I have not figured out how to navigate to my file share via Windows Explorer through my VPN tunnel. 

Is this possible?

NSGs not working in Azure Classic as expected

I'm having problems getting Network Security Groups to work in Azure classic? I’ve removed some existing endpoint mappings and switch to NSGs so I can block some outbound ports.

I’ve created the classic NSG, added some rules, removed the endpoint mappings from the VM and linked the NSG to a classic VM but I can’t connect to it externally. I have a similar NSG setup for ARM servers in the same subscription and that works as expected.

The network monitoring tools, like IP View, seem to be ARM only, so any ideas?

Hi,

We have many on-premise offices across the globe and now are moving to Azure. We utilize many Azure subscriptions in different Azure regions.

The problem is that configuring VPN between each on-site office and each Azure Subscription in different Azure regions becomes a nightmare.

Any corporate gateway or any other simplified solution for this is possible?

Thanks

I was asked to post my problem here by ^PB on Twitter (See https://twitter.com/AzureSupport/status/1023333881104277504)

I am running against an error when I try (on different Azure accounts) to execute the commandlet New-AzureRmVirtualNetworkGateway, even if I use the 1st example given on the Docs page here: https://docs.microsoft.com/en-us/powershell/module/azurerm.network/new-azurermvirtualnetworkgateway?view=azurermps-6.5.0#examples

$Gateway.Name = MivexLabAzGateway

$ResourceGroup.Name = MivexLabAzResourceGroup

$Gateway.Location = West Europe

This is the error I get (with debugging on):

I think I am going crazy, because I was able to create and use the VPN gateway before! But trying to troubleshoot with different accounts does not get me any further, and trying to do exactly what is done in the example (except the location to west Europe)

Please let me know if you actually need the authentication part.

Hi

I'm trying to migrate a VNET with a VPN Gateway from ASM to arm. However when I run 

$validate=Move-AzureVirtualNetwork -Validate -VirtualNetworkName $vnetName
$validate.ValidationMessages

I get an error which has no details about what is wrong. See below (I've replaced the VNETNAME and local Network Site Names for anonymity reasons.

ResourceType       : VirtualNetwork
ResourceName       : "VNETNAME"
Category           : Error
Message            : Migration of virtual network: "VNETNAME" failed as the address prefix 192.168.50.1/24 of local network site "SITENAME" is invalid. Please fix the network configuration before trying to migrate.

Does anyone have any idea how I can fix this?

Best regards,

Jan
