Multiple loopback interfaces

[Erik Norgaard]

Hi,

I need to setup a testing environment to properly test a new firewall 
ruleset, usually I'll install it on the machine and test it in a closed 
environment, but this time I don't have the machine.

Is it posible or advisable to create multiple loopback intefaces or are 
there other suggestions on how to do this?

Cheers, Erik
