Re: How do I prevent DNS leak through VPN? DNS leaks...
I assume you're talking about where the dns requests go out to the local ISP even though other traffic gets sent via the tunnel (happens with typical MS-PPTP setups for example).
If you're using a VPN to prevent people seeing what you're browsing (eg if you're in a country where you don't want the government to see what you're accessing or you're using the VPN to access sites which the government blocks) then this kind of DNS leak allows a good idea of where you're browsing to... and also allows for a censor to change the address that is returned, leading your PC to who-knows-what-site.
Otherwise, leaking of local addresses is as stefaanE said, much less of an issue. Not information I like to get outside my firewall but not a disaster by itself (though of potential use to hackers trying to exploit any weaknesses your firewall does have)
