OpenVPN not acquiring IP on mac client

view full story

http://serverfault.com – I have an interesting problem. I can confirm that the OpenVPN server is working because I can connect successfully on other Windows machines. On my personal mac laptop though I can connect but the workstation never receives an ip from the server. I have tried all the mac OpenVPN apps (OpenVPN Connect, Viscosity, Shimo.) They all connect successfully, but I have no IP on the TUN/TAP device. I have also tried reinstalling/uninstalling the drivers as well. The machine is now running on Mountain Lion although I was having the same issue in Lion as well. Any ideas what could be causing this issue? (HowTos)
