openvpn pushed dns get lost by local dhcp

[amadom]

Hello, I'm trying to configure an OpenVPN client (using ubuntu network manager). Everything is working perfectly except that the openVPN pushed DNS get overwriten by the local DHCP client. The file /etc/resolv.conf get changed to the original one (before the VPN went UP). So I cannot access the remote DNS server to resolv.

Any help will be greatly appreciated.

if you're using networkmanager to manage your local network as well then this should not happen ; I'm using NetworkManager 0.8+ on Fedora to manage both eth0 and my VPN connections and DNS resolution works OK (using default settings).

Thank you for your reply.

I will look the DHCP server side.

Thank you !
