in data panel, this is the traffic end in xds, traffic redirect to 127.0.0.1:some-port
user process should listen to 0.0.0.0 to make the traffic redirect work.
but in some case, user process listen to a specific pod ip, like 172.18.2.139, result to traffic failure.
this case may because of some security consideration, in some old project.
is there any thing to do to make this case work?
