     I can run traceroute
    against other systems but not throughput and latency.(details posted 
below) I
    can reproduce this issue if I test the other way around. Network and 
firewall
    is proved not the issue. 
    ...
    Note: for throughput test, it will run successfully if we manually open up
    port 5201 on the remote server.

Trace runs without the cooperation of services on the remote system.  
Throughput requires port 5201 on the remote system to be reachable to reach 
the server side of iperf3.  Having those measurements start working with you 
open the port manually means the firewall is misconfigured.

Barring someone or something making changes, systems installed as toolkits 
and having the perfsonar-toolkit-security package installed should have 
properly-configured firewalls.  Systems built using other means need to have 
their firewalls configured according to the table on this page:  
https://docs.perfsonar.net/manage_security.html.
