Hi All, Thanks for having me.
Kind of a noob here, but learning... I might have the terms wrong which is why nothing showed up in the search results on this site.
I would like to basically NAT an IP from a specific interface to a IP the rest of the router can see. After one is working I would like to replicate this on other ports (but same IP on the device plugging in) but different NATed ip. Also reachable by the rest of the router. I have seen this asked a few times on google and it seemed like the generic response is why would you want this. Let me give you my scenario:
(IPs have been replaced)
I have a existing network on 192.168.0.1. I have two devices I would like to test and communicate with. These units both are static IPs at 192.168.1.1 from the factory. To change these to unique IPs will mean code rewrite and custom FPGA images. If these units need to be replaced in the future, it will mean someone has to go through the same process. I would like to say just plug the unit into ETH5 and it should now be IP 192.168.0.2 (from the original network) or plug the unit into ETH4 and the unit should now be 192.168.0.3. No matter what the MAC is, as long as it has the same source IP and on that port. To further complicate I also have a small PC on the same bridge that will want access as well as WAN side inbound connectivity.
I am trying to work out the config on a hEX s RTR. I would appreciate and help you guys could provide. Or if I am using the wrong terminology drop a few hints.. eventually I will get a clue.
