| Re: How do I prevent DNS leak through VPN? DNS information is meant to be public, so leaking it cannot be a big security threat.
If you're talking about leaking internal DNS information, it hardly constitutes a threat, especially if you're using the customary private address ranges (10.x.x.x and friends). These ranges aren't routed on the Internet, and hence cannot be used as attack vectors.
The real security risk would be to use public addresses for internal systems, and not providing proper protection to these systems (especially if they are Windows based). In this case, leaking DNS information through a VPN is the least of your worries.
Take care,
