[Discuss-gnuradio] UDP do not work correctly

[feldmaus]

 Hi Gnuradio People, :-)

I tried to get the <UDP sink> and <UDP source> to work.
But it didn't work as it should. The FFT Plots only
shows a white screen. The CPU of my Work PC is under
100% and my Server PC too. Should this be a Problem of
<threads> ?
I have a network traffic between the connected pc's with
about 300Kbyte/s.

Do you have any hints for me?

Specification:
Work PC:
+ IP 194.94.26.158
+ Firewall with open UDP Port 13130:13133

Server PC:
+ IP 192.168.111.67
+ Firewall with open UDP Port 13130:13133

The Firewall was tested with <nmap -p 13130-13133 -sU IP-ADRESS>.

So i created a Flow Graph:

###SERVER PC###
[SIN Source]--\    /-->[USRP Sink]
              +-->+
[COS SOURCE]--/    \-->[UDP Sink 1]

SETTINGS for UDP Sink 1:
  Local IP Address: 192.168.111.67
  Port: 13130
  Remote IP Address: 194.94.26.158
  Port: 13132


[USRP Source]-->[UDP SINK 2]

SETTINGS for UDP Sink 1:
  Local IP Address: 192.168.111.67
  Port: 13131
  Remote IP Address: 194.94.26.158

###WORK PC###
[UDP Source1]-->[FFT Plot TX]

SETTINGS for UDP Source1:
  IP Address: 194.94.26.158
  Port: 13132

[UDP Source2]-->[FFT Plot RX]

SETTINGS for UDP Source2:
  IP Address: 194.94.26.158
