Andy,

XORP implements only the control plane, so all filtering will happen
in the data plane (e.g., inside the kernel).

If you want to configure the filtering inside the kernel, currently
you would have to use external software (e.g., ipfw for firewall
configuration on FreeBSD). Though, in the future you would be able
to configure it through the XORP configuration.
