I am working for a company remotely. They set up a openVPN for me to access their SVN and

whenever I try to access internet web pages, I always got "DNS address could not be
found ".
I have two virtual machines on my this machine, one is Windows 7 and one is
Linux. The strange thing is both of the virtual machines have no problem to
reach out to the internet web pages.
There is no difference if I run openVPN GUI as administrator or not.
anybody can help me this issue?
Depending on the openvpn server setup, it's possible that they are
redirecting all traffic to the VPN ("redirect-gateway") and not permitting
Internet access while the VPN is up.
This is not a generic OpenVPN issue, it's something in the way the server
is sending configs to the client, so you need to check with that company
whether this is the expected effect, or a bug.
without config files and client-side logs it is impossible to tell exactly what
is happening, but my guess is the following:
- when the VPN is up, your host Windows 7 OS can no longer reach outside web
servers (DNS errors).
- VMs on the same host *can* each outside web servers; most likely these VMs have their own internal DNS server setup that is
not affected by the VPN tunnel
This leads me to believe that the VPN server pushes a new DNS server address, which does not do DNS forwarding/resolving outside
of your company. Thus, your host OS ends up in a situation where it no longer can resolve openvpn.net ; however, I further
guess that you can still reach public IP addresses . On your Windows 7 host, open a command shell and try
ping 104.20.194.50
If that works, then your DNS settings are screwed up by the VPN config - a
client-side log with 'verb 4' set should verify this.
If the ping did not work, then I am curious how your VMs *are* able to access the outside network while the VPN is up - again, a
client-side log with 'verb 4' set should provide a lot more info.
