Trying to figure out how to create a U-Turn so that a web server we have on our DMZ is accessible to all hosts (whether on the inside or another host in the DMZ) via its public IP. See attached crude drawing.
We have split DNS for this particular zone, but we need to keep the A record for this particular host consistent inside and outside. Ordinarily I'd just use the DMZ address on the internal zone, but the developer for a particular piece of software we are deploying insists that doing a u-turn is the only way to ensure it works properly.
Can anyone help me out with how to create a 1:1 NAT that is accessible by the outside IP no matter where the traffic originates?
