You can do that on systems using OpenBSD-derived "pf" without any extra
applications, but I believe the original request was for having boxes
in two different cities: "A primary server in Ashburn, VA and a
backup in Long Island, NY." Hard to do that with a single IP address
:-) due to the way IP routing works.
Oh ya -- I totally missed that part. That won't work as that IP has to
be available in the same network (i.e. same switch/router).
