Hello everybody ,
I made a px server on a hetzner server for test.
I can not reach a port defined as open on a VM ( here : VM 254 , ip 192.168.50.54 , port 21116 , protocol tcp )
Here is network configuration :
Form the px host , I can reach it :
But from outside, that doesn't work :
Any idea ?
Regards,
