To fix this error, a [one-time registry change](https://documentation.meraki.com/MX-Z/Client_VPN/Troubleshooting_Client_VPN#Windows_Error_809) is required because the VPN server and/or client is behind NAT (e.g. home router).

### Windows DNS leaks and IPv6
Windows 8.x, 10 and 11 use "smart multi-homed name resolution" by default, which may cause "DNS leaks" when using the native IPsec VPN client if your DNS servers on the Internet adapter are from the local network segment. To fix, you may either [disable smart multi-homed name resolution](https://www.neowin.net/news/guide-prevent-dns-leakage-while-using-a-vpn-on-windows-10-and-windows-8/), or configure your Internet adapter to use DNS servers outside your local network (e.g. 8.8.8.8 and 8.8.4.4). When finished, [clear the DNS cache](https://support.opendns.com/hc/en-us/articles/227988627-How-to-clear-the-DNS-Cache-) and reboot your PC.

In addition, if your computer has IPv6 enabled, all IPv6 traffic (including DNS queries) will bypass the VPN. Learn how to [disable IPv6](https://support.microsoft.com/en-us/help/929852/guidance-for-configuring-ipv6-in-windows-for-advanced-users) in Windows. If you need a VPN with IPv6 support, you could instead try [OpenVPN](https://github.com/Nyr/openvpn-install).
