Default Can I spoof???

Hi guys,

as said I'm doing my graduation with PF.

Here's the scenario:

VM connected to the INT_IF (PF), then PF has another IF to go outside (actually my phisical router).

I've installed 2 VM, 1 win7 and the other BackTrack 4.

I set up that ONLY Win7 machine can ping and surf, everything works because if I try a ping with Win7 it successes, with BT it fails.

Now the "problem", in pf.conf I wrote the "anti spoof" rule but it doesn't seem to be working.

Win7 has the IP of and BT has, from BT I can launch this command: sing -S and I have replies!!!

I'm sure that I'm wrong somewhere... please look at the pictures that I've attacched.

Let me know something.
