Problem we have:
We are about to switch web servers and those in power want it to be
'seamless'. For various reasons a short ttl was rejected.
Because we run the two servers in our dmz, the redirect from server (old)
to server (new) has to use the external ip not the internal one.
Whilst the external one works for the internet, we're blind from the
network (again various reasons) whilst its on, so I need to fid a way to
get the redirect ip picked up by our internal dns and somehow translated to
its dmz one.
The obvious solution, I thought, was a cname 'www2' for the internal ip
that could then be used by the A record for the external address.
Seems not, though. Is there another way around this one?
in simple terms we need to do
'new server external address' -> 'new server internal address'
where the external one is used by IIS redirect, and networked PCs cannot
get to this address.
