I think I found out the possible source of problem. Toda I found out the following issues with “Packet Encoder/Decoder” blocks. I replaced the TUNTAP PDU block with a Wav File Source and Audio Sink blocks at the transmitter and receiver, respectively. I noticed that always the receiver side must be executed after the transmitter side. Otherwise I cannot hear any audio. Now I wonder how I can solve this problem. BTW, I also tried to use the gnuradio tunnel.py example in /example/digital/narrowband; But it won’t work and it always give an error. The other tunnel.py example in /examples/digital/ofdm, however, works fine. But still I cannot ping the machines. Cheers.

Did you bring up the interfaces? Are the IP addresses of the tuntaps reachable with a ping from your PC? -- Cinaed > > > > I use USB GNURadioLiveDVD > <https://wiki.gnuradio.org/index.php/GNURadioLiveDVD> as the OS. > > > > I wonder which part is not right.
