Does NI MAX work through NAT?

[MzazM]

Hello,
We have a cRio behind a router with SIM card. Router is configured to forward the following ports to cRio according to the articles here (link 1 and link2).

- TCP 52725 / 3580 / 80 / 44516

- UDP 44515 / 44525 / 5353 

The web UI works well with this setup, as well as a web service that is running on the cRio, same for SSH.

NI MAX does not work. NI MAX finds the device at first, but after few seconds it transitions from the "connecting" state to a red-X icon (see screenshot).

Before that it discovers the serial number and a few other parameters (not all).

Has anyone accomplished something similar?
Actually while searching for this, I found a message in the NI forum from a user with the same issue (from 2015) and another one from 2010. Nothing afterwards.

Any idea? Thanks!

Any update to this? I am attempting to work through a similar issue and cannot find any other useful information online. I see the same behavior that you described above, MAX sees the cRIO, then once it adds it to the remote systems is changes to disconnected.
