Run the following PowerShell command to list active sessions: Get-AzVirtualNetworkGatewayVpnClientConnectionHealth -VirtualNetworkGatewayName -ResourceGroupName Ĭopy the VpnConnectionId of the session that you want to disconnect. To view and disconnect a session using PowerShell: If you have one of these gateways, use the PowerShell method that's described in the next section. Select "…" for the session you want to disconnect, then select Disconnect.Ĭurrently, you can't use this feature in the portal for VpnGw4 and VpnGw5 SKUs. You can view all current sessions in the windowpane.
Under the Monitoring section, select Point-to-site Sessions. To view and disconnect a session in the portal:
#DISCONNECT AZURE POINT TO SITE VPN UPDATE#
Then update the virtual network gateway IPsec policy.Connection source info is provided for IKEv2 and OpenVPN connections only. If the VPN device has Perfect forward Secrecy enabled, disable the feature. The Perfect Forward Secrecy feature can cause the disconnection problems. Step 7 Check whether the on-premises VPN device has Perfect Forward Secrecy enabled If the Internet facing IP address of the VPN device is included in the Local network gateway address space definition in Azure, you may experience sporadic disconnections. Step 6 Check on-premises VPN device external interface address If the number of Azure virtual network subnets multiplied times by the number of local subnets is greater than 200, you see sporadic subnets disconnecting. The Policy-based virtual network gateway has limit of 200 subnet Security Association pairs. Step 5 Check for Security Association Limitation (for policy-based virtual network gateways) This traffic may also be regulated via firewall rules, as with any other network interface. Systems at Site A can reach servers or other systems at Site B, and vice versa. Make sure that the on-premises VPN device is set to have one VPN tunnel per subnet pair for policy-based virtual network gateways. IPsec Site-to-Site VPN Example with Pre-Shared Keys¶ A site-to-site IPsec tunnel interconnects two networks as if they were directly connected by a router. Step 4 Check the "one VPN Tunnel per Subnet Pair" setting (for policy-based virtual network gateways) This makes it appear that the VPN connection is unreliable for some traffic and good for others. Step 3 Check for User-Defined Routes or Network Security Groups on Gateway SubnetĪ user-defined route on the gateway subnet may be restricting some traffic and allowing other traffic. Verify that the Security Association settings match.Make sure that the virtual network, subnets and, ranges in the Local network gateway definition in Microsoft Azure are same as the configuration on the on-premises VPN device.Step 2 Check the Security Association settings(for policy-based Azure virtual network gateways) For more information, see Editing device configuration samples. Make sure that the VPN device is correctly configured.If the VPN device is not validated, you may have to contact the device manufacturer to see if there is any compatibility issue. Check whether you are using a validated VPN device and operating system version.Step 1 Check whether the on-premises VPN device is validated Troubleshooting steps Prerequisite stepĬheck the type of Azure virtual network gateway:Ĭheck the Overview page of the virtual network gateway for the type information. This article provides troubleshoot steps to help you identify and resolve the cause of the problem.
You might experience the problem that a new or existing Microsoft Azure Site-to-Site VPN connection is not stable or disconnects regularly. Troubleshooting: Azure Site-to-Site VPN disconnects intermittently
