Comment 59 for bug 37239

Well, since recent auto-updates and some playing with Firestarter, wireless vpn connections work fine through NM. Disabling the firewall seems essential for the VPN connection to work..... For wired vpn connection I use the OpenVPN config GUI, which also works fine. I could imagine that cleaning out resolv.conf contents is a measure to avoid accidential DNS calls outside the tunneled connection, with resulting breach of security. NB: I am no programmer either, just a VEP.

Best wishes for a happy new year,
