If you are using a version of OpenVPN older than v2. 9
Please note that as this problem normally only affects windows clients, only solutions for Windows appear
here.
3 basic steps to fix the problem;
Before connecting to the VPN, set static IP address properties if you are using DHCP
After connecting, remove DNS settings for the primary interface
After disconnecting, switch back to DHCP if neccessary or reapply original static DNS servers
Solution A – Automatic
If you are using OpenVPN on Windows XP/Vista/7 then a fully automated solution is available.

After installation, when you connect to a VPN server, a batch file will be run executing the 3 steps
above.
Three scripts are generated for each OpenVPN configuration file;
– executed when you initiate the connection but before the
connection is established – Calls – If any active DHCP adapters exist, switch to static
– executed when the connection is established – Calls –
Clear the DNS servers for all active adapter except the TAP32 adapter
– executed after the connection is disconnected – Calls
– Reconfigure adapters back to their original configuration
Solution B – Manually clearing the DNS
The solution below does not switch the adapter to static if you are using DHCP. If you do not
switch to a static IP configuration and your computer renews its IP address whilst connected to
the VPN, the DNS settings may be overwritten. It is highly recommended to switch to a static
IP configuration.
Open the command prompt () as an administrator.
Before connecting identify the name of the connected network interface. In the case below it is
“Local Area Connection”
netsh interface show interface
Connect to the VPN. Once connected proceed to the next step.
Flush the DNS resolver cache
ipconfig /flushdns
Disable the DNS configuration for the Interface identified in step 1
netsh interface IPv4 set dnsserver “Local Area Connection” static 0. 0. 0 both
Test for DNS leaks.
After disconnecting, reconfigure the adapter to renew the previous DNS settings
netsh interface IPv4 set dnsserver “Local Area Connection” dhcp
Once again, flush the DNS resolver cache.
Done.

Standard vs Extended test

Standard vs Extended test

In early 2014 the site was upgraded in order to more comprehensively search for DNS leaks and as a result two separate tests were created.
The DNS leak test works by sending your client a series of domain names to resolve within a specific test domain. Each request is sent from your client to your configured DNS server. Even if you have configured a single DNS server, there may be many other servers that the request is passed on to in order to be resolved (normally to load balance the requests). For example if you configure Google DNS then you will often find 6-10 Google DNS servers which are fullfilling the DNS requests. The Standard test performs 1 round of 6 queries for a total of 6 queries. This should be more than sufficient to discover if you have a DNS leak. The original test prior to the 2014 upgrade did 3 queries. The advantage of this test is that it is fast. Use this test to quickly check for dns leaks when you connect to your VPN service.
The Extended test performs 6 rounds of 6 queries for a total of 36 queries. This high number ensures that all DNS servers are discovered. However for the purposes of discovering if you have a DNS leak this is not normally neccessary and can take 10-30 seconds longer to complete. If you have strong anonymity/privacy requirements you can choose the extended test just to be certain.
