[isf-wifidog] regarding an ubuntu gateway

I just setup wifidog on an ubuntu 8.04 machine. There I setup both,
the gateway and the auth-server.
Then, I setup a virtualbox virtual machine which is supposed to use
the wifidog gateway in order to gain access to Internet.
The problem is that wifidog starts, setup the iptables rules, but the
virtual machine keeps on having access to Intenet.
The setup is something like this:
<internet> - <ubuntu-gw> - <ubuntu-virtual interface>  -
<virtual-machine interface> - <virtual machine>
Without wifidog, the virtual machine is able to surf the Internet
thanks to an iptables MASQUERADE command. As soon as the wifidog is
started, I asumed the conection between the virtual machine and
Internet should be interrupted but that's not happening.
Could anyone point me on what i'm doing wrong?
I installed wifidog using the cvs version and setup the validation
grace period to 2 seconds.
