dns leakage on vpn?

#1 Post by jimm »

Hi all,

Set up a VPN thru network manager. Installed two DNS servers known for privacy.

When I engage the VPN and go to websites** to check my vpn "footprint", I can see 0, 1 or 2 of my chosen DNS servers. If I pull up a terminal and type "cat /etc/resolv.conf", I can see my two chosen DNS servers, but I also show another DNS entry -- "10.19.0.1". Looking up this last entry says it's a "private network". Another source says it is a local network and is not accessible to the internet.

If I ping the address 10.19.0.1, I get ping times on the order of 1/4 second (~250 ms). Does this add up?

What's your router's IP address on your LAN?

Looked up some commands on cyberciti.biz/faq/how-to-find-gateway-ip-address/

ip r
default via 10.18.0.1 dev tun0 proto static metric 50 <---- vpn
default via 192.168.1.1 dev eth0 proto dhcp metric 100 <---- routers configuration area

From the output of the IP command, that makes sense. My VPN exit was in Europe which would account for the long ping time. Thanks.
