I recently changed the private IP addresses of my network. I changed from a 192.X.X.X network to a 10.X.X.X.
A program written by an old consultant of ours was hardcoded to reference a server at 192.168.2.18. This server still exists, but is at a new IP address now. The authoring consultants is no longer available and the program won't run.
Is it possible to fool my system into sending all requests for the 192 address to the new IP address?
I've tried to do this with a SonicWall NAT policy, unfortunately it didn't help. While I could ping 192.168.2.18 and get replies from 10.1.1.8 (The new IP address of the same server), I couldn't access SQL services with the same port. Nor could I access anything that needed a designated port.
Of course, this programmer should have written the program to reference a hostname, but if I can redirect a request for one IP address to a different IP address, this will get us through the night.
All help is appreciated.
