rc.openvpn on -current (no DNS)

I'm trying to start a VPN connection through the /etc/rc.d/rc.openvpn script on current. I'm doing:
Code:sh /etc/rc.d/rc.openvpn start vpn.config(where vpn.config is a ovpn config file from the VPN provider). It prompts me for my username/pass, and then my DNS doesn't seem to work until I `rc.openvpn stop`. I have connectivity (I can ping 1.1.1.1 for example), but no DNS. I'm using NetworkManager to connect to home WiFi, am I missing something?
