A virtual or a physical i/f doesn't make any difference. What counts is the
ROUTING, and of course, the ipchains rules to allow/deny/reject from/to the
different addresses/networks...
Well, actually there _is_ a difference - virtual interfaces have a nasty
tendency to generate collisions, but I have 9 addresses on the internal card
and performance isn't a problem.
