What I can do is leave the old server up at its old address and have it
continue forwarding packets that are still sent to it from people who
didn't get the word, and contact them to get them to update before I
have to shut down the old machine. We'll send their inbound traffic
to them from the new machine, but it's anybody's guess if they'll get
it because of firewalling.
I really can't do anything about the outbound addresses being different
though, since the two machines are on distinctly different subnets and
I can't change the campus backbone. I've already had to hassle the
campus networking folks to get the RPF disabled, and I really don't
like to bother them.
