Location in Azure: B. Get-AzVirtualNetworkGateway

Location on Client Computer: D. ipconfig /all

To troubleshoot the issues reported by User1, you need to use the Get-AzVirtualNetworkGateway PowerShell cmdlet in Azure and the ipconfig /all command on the client computer. The Get-AzVirtualNetworkGateway cmdlet returns information about the virtual network gateways in a subscription or a resource group. You can use this cmdlet to verify the status and configuration of the VNetGW virtual network gateway, which provides point-to-site VPN connectivity for User1. The ipconfig /all command displays the IP configuration information for all network adapters on the client computer. You can use this command to check the IP address, subnet mask, default gateway, and DNS servers assigned to User1 when connected to the point-to-site VPN. This can help you identify any misconfiguration or connectivity issues that affect User1’s access to Azure resources.

To troubleshoot the issue reported by Blue Yonder Airlines, you need to review the IKEDiagnosticLog, which contains information about the Internet Key Exchange (IKE) protocol that is used to establish IPsec VPN connections. The IKEDiagnosticLog can help you identify the cause of the VPN disconnections and IPsec failure to connect errors, such as mismatched authentication parameters, incorrect pre-shared keys, or network connectivity issues. You can enable and download the IKEDiagnosticLog from the Azure portal or by using PowerShell commands

To resolve the issue with VM10, you need to remove the inbound security rule that has a priority of 100 in NSG10, which is blocking ICMP traffic from ASG1 to ASG10. The rule has a source of Any, a destination of VirtualNetwork, a protocol of ICMP, and an action of Deny. This means that any ICMP traffic from outside the VNet4 address space will be denied by NSG10, which is attached to subnet4. This prevents VM1 from pinging VM10 by using ICMP, as VM1 is in VNet1 and not in VNet4. By removing this rule, you can allow ICMP traffic from ASG1 to ASG10, as there is no other rule in NSG10 that explicitly denies it. Alternatively, you could also modify the rule to change the source to VirtualNetwork or the action to Allow, but removing the rule is simpler and more effective.
