[Discuss-gnuradio] Sending/Receiving UDP Data Over Internet

[Matias]

Hello,

We would like to send UDP data from a USRP over the internet to a remote
computer. The setup on the host side is:

USRP Source --> UDP Sink

And on the client side:

UDP Source --> Throttle --> WX GUI FFT Sink

This setup has worked on a local network using the client's IP address
"10.10.0.175:9000" with the UDP sink and UDP source. However, when using the
host's public static IP "166.149.xxx.xxx:9000", Gnuradio throws the
following error:


/Traceback (most recent call last):
  File "/home/matias/Documents/top_block.py", line 116, in <module>
    tb = top_block()
  File "/home/matias/Documents/top_block.py", line 76, in __init__
    self.blocks_udp_source_0 = blocks.udp_source(gr.sizeof_gr_complex*1,
"166.149.xxx.xxx", 9000, 1472, True)
  File
"/opt/gnuradio-3.7.3/lib/python2.7/dist-packages/gnuradio/blocks/blocks_swig5.py",
line 1974, in make
    return _blocks_swig5.udp_source_make(*args, **kwargs)
RuntimeError: bind: Cannot assign requested address/

Does anyone know how to resolve this? We are using GNU Radio 3.7.3 on a
virtual Ubuntu 12.04 LTS.

Thanks,
Matias Ponce
