IP ports used for COM Automation between Matlab and Agilent/Keysight logic analyzer?

Hi All,

First post here, hope it's in the right forum.

I've been using Matlab successfully for a while on a Windows 10 PC to communicate over ethernet with an Agilent/Keysight logic analyzer (which also runs Win10).

Does anyone know which IP ports this interface needs to use?

My I.T. organization recently tightened up the firewall policy for all machines on the network, and the logic analyzer is now rejecting COM connections from the client PC. (We can still ping the LA and login to it using Remote Desktop Protocol, so the network is not entirely broken.)

The I.T. Security support people started opening up a few ports at a time, based on what we see getting blocked in the log files, but every time we get one test to pass, the next run uses different ports and hangs the LA again. I've heard the RPC Server in this application might be expanding the ports it uses over time. We'd rather keep the security tight and not open all ports unnecessarily, but I'm afraid we'll be playing whack-a-mole for a long time if we don't.

Thanks in advance for any inputs you can provide!
