Not using PIA VPN through WiFi, the system is hard-wired on the LAN.

Wireless AP connected as well on the same switch.

Switch providing internet to the LAN devices.

pfSense installed on bare-metal workstation.

I tested this on two different days, and I woke up to no internet on any computer or device on my network. Uncheck the Automatic metric option and change the interface metric to 120.When I connect to the PIA VPN via the Windows 10 client, my internet gets disconnected after several hours and requires unplugging the cable modem to get my internet connection back up and working. Go to the Control Panel -> Network & Internet -> Network Connections, open the properties of your Ethernet connection, select TCP/IPv4 properties and go to the Advanced TCP/IP Settings tab. You have to increase the metrics of your LAN connections so that their values exceed 100 (in my example). You can change the interface metric from the Windows GUI, PowerShell or using the netsh command.įor example, you want your DNS requests to be sent over your VPN connection. For example, a LAN connection with the speed > 200 Mbit/s has the metric value equal to 10, and a Wi-Fi connection with the speed of 50-80 Mbit/s has the value of 50 (see the table ). Windows assigns metrics of IPv4 interfaces automatically depending on their speed and type. Thus, the lower is the value of the interface metric, the higher is the priority of the connection. So changing the interface metric allows you to send DNS requests over the connection (LAN or VPN) where name resolution is the most priority for you. You can increase the priority of a particular DNS if you make its metrics lower.

In Windows 10 Creators Update (1709) and newer, DNS requests are sent to all known DNS servers one-by-one (not in parallel). Set-ItemProperty -Path "HKLM:\SYSTEM\CurrentControlSet\Services\Dnscache\Parameters" -Name DisableParallelAandAAAA -Value 1 -Type DWord Set-ItemProperty -Path "HKLM:\Software\Policies\Microsoft\Windows NT\DNSClient" -Name DisableSmartNameResolution -Value 1 -Type DWord Or you can disable SMHNR using the following commands (in Windows 8.1): You can disable the SMHNR in Windows 10 via the GPO: Computer Configuration -> Administrative Templates -> Network -> DNS Client-> Turn off smart multi-homed name resolution = Enabled. It is not secure since the external DNS servers (specified for your VPN connection) can potentially see your DNS traffic (the leak of your DNS requests). By default, SMHNR sends simultaneous DNS requests to all DNS servers known to the system and uses the response it received first ( LLMNR and NetBT queries are also sent). Smart Multi-Homed Name Resolution (SMHNR) was added in these OS versions to get faster response to DNS requests.

In addition, a new feature of the DNS client for Windows 8.1 and Windows 10 should be mentioned here. In this configuration, you cannot resolve names in the connected external VPN network. It means that your DNS requests are sent to your local DNS servers instead of the DNS servers for VPN connection. So the DNS traffic goes through the interface with the lower metric value. The screenshot above shows that the local Ethernet connection has a lower metric (25) than the VPN interface (100). Get-NetIPInterface | Sort-Object Interfacemetric For example, your VPN connection works in the the Split Tunneling mode (you want to access Internet from your LAN and your corporate resources over VPN).Ĭheck the values of all network interface metrics from PowerShell: You must understand that Windows sends a DNS query from the network interface, which has the highest priority (lower value of the interface metric). If you are using Split Tunneling (the “ Use default gateway on remote network” option is unchecked) for your VPN connection, you can access the Internet from your local network, but you cannot resolve DNS addresses in the remote VPN network (IPv6 disabling does not help here). I found some recommendations on disabling IPv6 protocol for your local (LAN) interface and it would help if you want to use the Force-Tunneling mode. The fact is that Windows 10 is trying to resolve host names in your local network through the DNS servers specified in the VPN connection settings. They are available only by IP addresses, but not by their host names. At the same time, you can ping any resources on your LAN (try to ping your gateway, neighboring computer or printer IP address).
