IP forwarding?

["Jason Lim" <maillist@jasonlim.com>]

Hi all,

I am trying to come up with a solution to a network problem, but i haven't
got much idea how to do it. If you could just give me a couple of
suggestions I could search on Google and research further.

I basically have 2 networks, each with 32 IPs.

Say the first network is 1.2.3.1-32
and the second network is 5.6.7.1-32

Is there a way to make it so requests for 1.2.3.1 go to 5.6.7.1, and 1.2.3.2
go to 5.6.7.2, so basically map 1.2.3.1-32 to go to 5.6.7.1-32?

They are two separate neworks, each with their own network and bandwidth.
But basically i'd like to have it so that 1.2.3.1 is the IP i give to
people, but behind the scenes, the data is transferred transparently to the
server at 5.6.7.1 instead?

So basically:
VISITOR --> 1.2.3.1 --> 5.6.7.1 --> SERVER

It doesn't matter if the SERVER is configured with 1.2.3.1 or 5.6.7.1 as
it's IP. But the visitor should only know about 1.2.3.1.

Essentially, this is what you would do if you were moving datacenters or
something, as a temporary solution.

Hope someone can help! I tried looking at IP MASQURADING but that doesn't
seem to be the right thing ,and IP FORWARDING doesn't seem right either. Am
I missing a solution?

Thanks in advance!
