MY client has ERP servers and ISA servers in a single DMZ but now wants to place the ERP Servers on one DMZ (say DMZ1) without changing their IP Subnet and place the ISA Server on another DMZ (say DMZ2) and a diffrent IP Subnet. The problem is that he has around 1500 users on the LAN using the ISA Server and doesn't want to change the IP Address of the ISA server on all the PCs.
What he wants instead is that a translation should be created for the ISA so that when the inside users try to access the ISA server using its old IP Address (which is now part of DMZ1 - ERP DMZ) the request should be forwarded to the DMZ2 interface (where the ISA server now resides physically).
I have tried to convince him to change the IP Address of the ISA in the client PCs but he is not accepting it.
How can this be achieved through static translations.
Thanks in Advance!
