Hi donza,

What does your "scutil --dns" output look like while connected to your VPN connection (when you are having DNS trouble)? Information about running this command can be found in the "Checking Which DNS Servers Are Being Used" section at:

Hi James,

"Resolver #1" has my ISP's DNS servers, which won't answer when VPN is active.
"Resolver #2" has my VPN connection's valid DNS server, which answers if I manually query "dig @x.x.x.x http://www.google.com A" where x.x.x.x is the DNS server in "Resolver #2".

So it looks like that for some reason GUI apps don't even attempt to use "Resolver #2".
Below is the output (with actual IPs hidden):
Code: Select all
DNS configuration

resolver #1
  search domain[0] : tun0.viscosity
  search domain[1] : Cisco
  nameserver[0] : a.a.a.a
  nameserver[1] : b.b.b.b
  if_index : 4 (en0)
  flags    : Request A records

resolver #2
  domain   : tun0.viscosity
  nameserver[0] : x.x.x.x
  flags    : Request A records
  reach    : Reachable
  order    : 100400

Hi donza,

It sounds like you have the "Apply DNS settings simultaneously" option turned on (under Preferences->Advanced). Turning this option off should give you the behaviour you're after.

Thanks James! I'm not sure when that setting got enabled, but disabling it did the trick.

Hi NanoG6,

It appears there is a bug in OpenVPN 2.3.5 if encryption is disabled, which is what you're running into. We'll see if we can come up with a patch or workaround for it - in the meantime I'd recommend dropping back to the stable release which comes with OpenVPN 2.3.4.

Cheers,
James
