I mean exactly that: use different frequencies like in an FDD system. Set the transmit frequency to f_tx and the receive frequency to f_rx. When you run "tunnel.py -h", you'll see options "--tx-freq" and "--rx-freq". Just setting "--freq" automatically sets tx_freq = rx_freq = freq. > Also recently I did following.

First check your routing table, but your system is probably being smart and just passing packets over the loopback device. You can use wireshark/tcpdump to check this out. > If it was within the system then I might have made a wrong screen cast on > this tunnel thing which I recently uploaded on my channel > > http://www.youtube.com/watch?v=CLvV2Q7vh-o > > PS : Video is a bit blurred but one can easily make out Tom _______________________________________________ Discuss-gnuradio mailing list Discuss-gnuradio@gnu.org https://lists.gnu.org/mailman/listinfo/discuss-gnuradio
