Hi folks, I’m newish to IPFire as well as Linux. I apologize in advance for my ignorance!
If possible, I’d like to connect two network segments, with different IP addressing schemes, and NAT/Route them into the Green Zone. This post, https://www.ipfire.org/docs/configuration/network/zoneconf/bridge3nic2green, shows how to bridge multiple NICs, but I believe that consistent IP addressing is implied.
The Red Zone will be connected to an existing OT (Operational Technology) network with yet a different addressing arrangement. For programming purposes, a workstation PC in the Red Zone needs to access PLCs located on the two network segments for the purpose of programming.
The machine on which I’ve implemented IPFire is a mini-PC with 16 Gb RAM and a 512 Gb SSD. I have a 4-port Ethernet adapter plugged in to it via USB. Each of the four ports has its own MAC and IPFire recognizes them just fine.
I know that I could accomplish the same task using a couple of NAT modules, but they cost from $800 up and my company is having a lean year.
Does this project seem doable? If so, any help is greatly appreciated!!.
