I have ubuntu 14.04 server installed inside a VirtualBox VM running on OS X 10.10. My goal is to configure OpenVPN on ubuntu in order to access via the host system. This is a testrun for a OpenVPN installation on a remote server.
In order to do so, I followed this tutorial: https://www.digitalocean.com/community/tutorials/how-to-set-up-an-openvpn-server-on-ubuntu-14-04
Everything went OK, and I could initially connect via Tunnelblick to the server. However 60s later Tunnelblick tells me that I might have lost internet connection due to a misconfigured openvpn config. So I disconnect and stop tunnelblick.
Unfortunatelly I can no longer access my VM from OSX. A tracert shows, that it tries to connect first over my router and then second to the internet provider which is unecessary. The regular way would be just one hop to the IP as specified inside /etc/hosts
After rebooting the mac everything is fine again. I can reproduce by trying to connect via tunnelblick again. Same thing and I have to reboot.
Does somebody have an idea how to fix that?
