 Yes, it is possible. From the comments that you've already
received, you now know that it isn't advisable though. What
you want to look into is using ifconfig to create virtual
interfaces off of your existing physical interface (NIC).
You'll be able to do what you want, but also remember that
performance will also take a hit since all local and
external traffic will be going over the same interface.
Just try to make this as temporary a solution as possible.
 Search through the ifconfig man page for the string
"logical-unit" and you'll see what you need to do.
