It sounds like you need to host more than 256 virtual domains on your FreeBSD
machine, no?

If you try the scheme that your are thinking of doing, your probably going to
freak out your router, because you will be having arps with the same
MAC address coming from both subnets.  It would be interesting to try it
and see what happens, though.

What I'd suggest that you do is move to using a class B address with a
standard class B subnet mask of 255.255.0.0   If you have that many clients, you
should be able to obtain a class B from your provider.
