What's the best firewall setup to prevent VPN leaks in Windows?

I'd appreciate links re preventing VPN leaks in both Windows XP and 7-8.

Which works better, Comodo or Windows firewall? Or

 

I prefer Online Armor myself, but if you are trying to prevent VPN leaks then you should try VPN Check Pro. I have been using it for a little over two years now. If your VPN looses connection it will alert you, and it will also shut down any application you are using like your web browser, P2P applications, mail clients, etc.. to prevent them from exposing your real IP address. It works really well. -http://www.guavi.com/vpncheck_pro.php-

OK, so now I'm looking for links re setting up Windows firewall, Comodo and/or Online Armor to prevent VPN leaks, even if the VPN client gets totally nuked.

I'd rather block all non-VPN traffic, except to/from the VPN server, without the need to block for each app specifically.

 

I do each app specifically, so no help. I know the Air and Bohle forums have how-to's on blocking ALL traffic.

PD

 

Here is a link to what I posted on this using Air. This comes from the Air forums. I can tell you that it works without fail.

 

Thanks

I found the Comodo instructions in AirVPN support, and also instructions for the Windows 7/8 firewall.

But I don't see anything coherent for OS X. Does anyone know, or have a good link?

 

For mac check here:

Thanks

 

Run OpenVPN in x32 or any OpenVPN client that uses 32x. Then use the fix here ( https://www.dnsleaktest.com/how-to-fix-a-dns-leak.php ), You don't need a firewall to block connection as this will do all the work for you. I have found nothing better for clients.

 

Thanks

For firewalling in Windows, the best source that I've found is -https://forums.comodo.com/firewall-help-cis/configuring-to-block-all-nonvpn-traffic-t91413.15.html.

For OS X, the best source that I've found is -http://thenewtech.tv/it/openbsd-pf-on-mac-osx-lion.
