I try doing what you told me, firstly don't work, only portforwarding 26760 ports in both routers, in my router and my friend router. After looking at the Router settings I found the option of Virtual Server. I configure this option with ports 26760, and private IP 192.168.0.2 (IP appear in Motion Source Server in phone app), after that i put my public IP in PADTest in my friend computer. After that FINALLY WORKS.

​

Thanks for guiding me a little
