Hi Tor,
My point was that if I define two different connections within NX client, both to the same host IP (differing only by TCP port number), then go into Advanced > UDP settings and define the preferred UDP port on one connection, that change _also_ changes the preferred UDP port for the other connection. This is consistent with the second comment on this thread, but it seems counterintuitive to me (unless there’s a good technical reason for doing things this way).
This obviously isn’t catastrophic — NX client falls back to trying all UDP ports in the defined range if the preferred port is busy upon initial connection — but it’s pretty counterintuitive that changing the setting for one defined connection should also change it for the others.
In any case, I’ve now defined the same preferred UDP port, and the same fallback range, for both connections to avoid this issue, and forwarded the entire range through the router.
Thanks,
