I have been looking for a howto, tutorial or something that describes me how to configure my firewall with a working openVPN connection. I have found none. I'm almost a newbie at networks, barely I got to configure a VPN, but I need to secure my firewall, and as I understand a VPN bypasses a firewall. Thanks in advance for your answers.

Is your system an OpenVPN server or an OpenVPN clieent? Do you want to firewall traffic coming to the box from external entities, or are you talking about firewalling traffic coming through the OpenVPN link?

These links contain pretty much everything you need:

But basically the easiest way is to create firewall rules that apply to the tun* interfaces ("tun+" in iptables config), you can restrict what goes into it or comes out of it no problem using this.
