Hello,
from my understanding when UDP is enabled, NoMachine first tries to open a UDP connection from the server side to the client. In case if this fails, then it tries the other direction. I think that I get the following message in the client log when the connection from the server side to the client can not be opened:
4596 4264 17:58:50 149.042 UdpProxyConnector/UdpProxyConnector: WARNING! Aborting current negotiation after timeout.
The timeout seems to be 5 seconds. Is it possible to somehow configure this timeout? Or to completely disable the connection attempt from the server side to the client (i.e., so that NoMachine first tries to open a connection from the client side to the server) ?
