I am trying to use ~40 server for mobile kits. These kits include a piece of equipment that has to have a hard coded IP address for the server. These kits go on mobile off line tasks and then return to upload/download data. We would like to have the ability for all 40 machines to use the same IP address, 192.168.1.10, and have the network be able to connect several at a time for the upload/download process. We have been using this system for years with the IP addresses being different.
I have 20 VLANs that I can use for separating the various servers, but I can't get any of the three Cisco routers I have to test with to allow me to put 192.168.1.1 on multiple sub interfaces. My plan was to setup 10-20 sub interfaces and NAT 192.168.1.1 to a 172.16.100.x address for each sub interface. Would I need to use a firewall or a different router for this?
