Forum: GNU Radio Tcp/udp connectivity btw two USRP.

Hi,
I have two usrp conncted to host A abd B respectively. I want to send 
packets from one host to other by using GnuRadio companion. I have setup 
a graph both hosts having packet encoder>Gmsk Mod>TCP sink
and on other host TCP source>gmsk demod > packet decoder

But this does not work.My hosts are connected to the same router via 
internet.

Best Regards,
