Thanks a million, Mangy!
This is very useful and helped me.(Fow now there are no WebRTC leak or DNS
leak with my openVPN as I had checked it)
However, this remind me another problem:
I found there may be a transparent DNS proxy from my ISP, even though I set
my laptop (Debian) using Google's DNS as well as on my router's DHCP
settings.
It turned out to be useless when I got a test on https://www.dnsleaktest.com/
-- still the DNS server from my ISP.....
sad...is it really unavoidable ? (if without using a VPN)
Gracias
