Ok I am trying to put gnatbox in an existing public IP network where renumbering is not an option. I will use some private IPs just for an example, however, all the real IPs are public. I am wondering if this is possible.
Let's say ISP has routed me 192.168.100.0/24 My router is 192.168.100.1/24 I want to put gnatbox in between my current servers which are on that same subnet. So EXT IF on gnatbox I assume could be 192.168.100.2/30 (this would allow it to talk to the router on .1) Now what would need to be entered on the PRO IF for an IP assuming all the servers reside on the /24 Also, I assume you would have to use IP Passthrough?? What would you enter in that part of the setup?
