<div dir="ltr">We have the same problem of running out of IPv4 addresses. We started using a router to do port forwarding from the control system (Badger, similar to Coral) to the ethernet relays. The control system, running on AWS, needs just one ip address,
blessed and approved by our IT department. The router gets messages on different ports, then maps ports onto the internal IP addresses of the relays. It works a lot like your home wireless router, but with the local addresses set to fixed values. The router
connects by wifi to some relays, and by hardwire to others. </div>
<div dir="ltr"><br>
</div>
<div dir="ltr">This requires the controller to allow address:port addressing, which is easy in Badger. Does FOM let you do the same thing?</div>
