We have an X310 and are trying to use the remote streaming option. We are using UHD v4.3.0.0 and trying to follow the example on the Device Streaming page in the UHD manual. The problem we are seeing is that the dest_port that we are setting is not being used, instead it seems like the x310 is picking a random port.
Here is the output of find devices:
[INFO] [UHD] linux; GNU C++ version 9.4.0; Boost_107100; UHD_4.3.0.HEAD-0-g1f8fd345

The X310 is connected to a Ubuntu 20.04 box with a 1 gige (x310 sfp0) and 10 gige interface (x310 sfp1) and here is those configs:

We used the python in the manual but change the stream_args to the following: stream_args.args = "dest_addr=192.168.40.1,dest_port=50007,adapter=sfp1,enable_fc=0"
When I watch the 10 gige interface (enp34s0f0) with tcpdump, I can see the port that the IQ data is being sent to change each time I run the python script. We are not sure why that is happening.
