This looks right, but also not.
I guess you would like to have the gateway address as the internal
virtual address witch will follow the active director, right.
Well this will work as long as this current machine is you director, if
this one fails and you fail-over to the other one your real server will
still try to use this broken machine as their gateway...
In this particular case this can also break the NAT, read the section
about real servers once again. Yes, read it carefully since it seams to
me it might be a bit confusing.
