Not really. You must specify a real interface (e.g. eth0). FIAIF will 
only allow multible zones for an interface when all zones for the said 
interface are non global (and you need a global zone for you internet 
connection). I do not believe that ipchains would accept interface 
aliases. Iptables cirtanly does not.

You should really buy another NIC. Routing from and to the same physical 
network is really bad and should be avoided.
