I know this is going to sound like a silly question, but I cant find any
information confirming or denying this:
We are currently using a 192.168.140.0/24 subnet in our internal
network. Recently, we have started using VMWare to do support of some
of our customers. We like to have duplicate setups of their servers in
our virtual environment. At the extreme, our customers have 7 separate
servers per site which we duplicate. We have recently acquired many new
customers and about half our what we term "multi-site". So there is a
possiblity of 14 or 21 servers. Each of which needing a static IP
address (because of the stupid way the software is written).
With the addition of these, plus the rest of our network, we are running
out of IP Addresses. I am thinking of dropping the subnet mask back to
a /23 or /22. To give me a usable range of
192.168.140.1-192.168.143.254.
I realizing because of CIDR, the theory of 192.x.x.x needing to be a
classC isnt an absolute anymore. But before I go through and make any
changes, I was wondering if anyone could confirm or deny that ISA will
handle this without any major issues.
Before you ask, yes, I plan on testing this before I roll it out. But
that wont be for a while. I figured if anyone had tried something
similar they could clue me in on any issues that they might have had.
If someone has tried it and it just wont work, then I will find another
alternative.
And yes, switching to a 10.x.x.x address was considered. But again,
with the way some of the software was written, the IP addresses would
need to stay the same.
