Hi all, we’re testing UDP shortpath. I’m following this guide to verify that the AVD client is connecting over UDP.
RDP-Shortpath greatly enhances user experience in Azure Virtual Desktop (AVD) using IGEL OS
However, I am not seeing “in the log file we see that we Connect to host 10.0.0.8:3390”. Is there another way to determine that the client is connecting over UDP? Here’s a snippet of the log output. TIA

You should see in the logs that it’s making a connection to the avd host ip on port 3390. It’s quite early when you connect to the session.
Thanks @member. I’ll try it again.
@member this is where the logs seem to start. Does that indicate it’s not using UDP?
If you grep 3390?
[13:26:40.333705] <140683969017600> {46c77a61-85b6-48ce-9eef-7e0639720000} RDP_WAN(INFO): UdpTrans::Connect – host:172.16.193.30:3390
Looks good. What does rdanalyzer say in session? (It’s a free tool)
says UDP (RDP-Shortpath). Thanks for the help!
@member Thank you for this tip! I did not know about rdanalyzer
