I cannot listen to my own stream, probably router problem

Please post a link to your DNAS.

Remember, machines on the same lan as the DNAS (you) need to use the lan ip of the DNAS to connect/listen.
Machines not on the same lan as the DNAS (the rest of the world) need to use the real, world-visible ip of the DNAS to connect/listen.

If your real, world-visible ip is 123.345.567.789, then everyone that is not on your private lan will use http://123.345.567.789:8000 (assuming default portBase of 8000) to connect/listen.

If your private lan ip is 192.168.2.25 (or similar, this is an example private lan ip address) then everyone that is on your private lan will use http://192.168.2.25:8000 (assuming default portBase of 8000) to connect/listen.

If you don't post your ip(s), then we can't help much further.
