First, this is considered bad network practice, and not recommended.
Second, this is very insecure.  Third, it is not easy, and requires
unsupported command line operations.

The correct way to do it is to add another interface, or use a V-LAN.
However, if you must do it, look for Chris's post about why this is bad
for instructions. :-)
