My team ran into problems with trying to debug remotely from NATed IP: when I start debug, it starts debug on another IDE on different computer.

We have all set the settings as docs tell us to (binding ssh to port 7869, etc), but when running debug from IDE, it started debuging in wrong team member's IDE. It seems that remote debuger cannot handle many binded ssh connections to same port, since after I changed debuger to listen to multiple ports and set my port to different from others, I could again debug.

Is there something we did wrong? Is there something we can do differently?

In php.ini change this setting
debugger.ports=7869, 7870,7871,10000/16

And assign to each developper his own port (i.e. 7869 for dev A, 7870 for dev B, and so on) in this mode it should be ok
