4 months ago you have multiple routing entries with the same destination but over different interfaces:

Issue Description
Unable to do iperf3 in Downlink for 5G SA mode with ZMQ mode.
Setup Details
PRETTY_NAME="Ubuntu 22.04.4 LTS" NAME="Ubuntu" VERSION_ID="22.04" VERSION="22.04.4 LTS (Jammy Jellyfish)" VERSION_CODENAME=jammy ID=ubuntu ID_LIKE=debian HOME_URL="https://www.ubuntu.com/" SUPPORT_URL="https://help.ubuntu.com/" BUG_REPORT_URL="https://bugs.launchpad.net/ubuntu/" PRIVACY_POLICY_URL="https://www.ubuntu.com/legal/terms-and-policies/privacy-policy" UBUNTU_CODENAME=jammy
Expected Behavior
I am using SRS RAN project for 5G testing in zeroMQ mode. I am running a dockerized version of the 5G core in a container. I am able to attach UE. I am able to ping in both directions DL and UL. I am able to do an iperf3 in uplink and able to do data transfer. In downlink, i am unable to do data transfer. I enter the container using the below command: sudo docker exec -it /bin/bash
Inside the container (running the 5G Core) i give the below command iperf -c 10.45.1.2 -p 5201 -u -b 50M -i 1 -t 60
On another terminal i give the below command: sudo ip netns exec ue1 iperf -s -i 1 I do not see any data only see the below
Server listening on TCP port 5001 TCP window size: 128 KByte (default)
Note: a) My output of route -n is given below
b) i am unable to use the command "iperf3 -c 10.45.1.2 -u -b 65M -i 1 -t 30" inside the container since it gives an error saying bad file descriptor
c) However when i run the command "iperf3 -s -i 1" inside the container for uplink traffic, then i get the data sent from UE to the UPF.
d) I am able to do a ping 10.45.1.2 from inside the container. (UE Ip address is 10.45.1.2)
e) Console output from the UE given below Active RF plugins: libsrsran_rf_zmq.so Inactive RF plugins: Reading configuration file ../configs/ue_zmq.conf...
