Don't do it. It is too much of a risk IMHO. Here is another link as to
why you should not do it:

Subject: How Secure is Layer 2 ???
Here is an interesting question. I want to configure a Pix FW to
provide a controlled connection between 2 Vlans on a switch (Cisco
3550 or 6500). There is no layer 3 routing enabled for the "outside"
interface vlan so in theory there should be no way to break out of
that vlan.
In theory I can't see a problem but perhaps I'm missing something???
Cheers
Trevor
