I don't think it's a firewall rule problem, but do you think opening up ports would solve my problem? I know the port I'm currently using on the TCP connection is port#: 1234 which deals with Mercurial and git default ports for serving Hyper Text.
When I had the UDP connection, I was using the same port (1234) except that in UDP, that port deals with a VLC media player. -----Original Message----- From: discuss-gnuradio-bounces+marcus.ward=jhuapl....@gnu.org [mailto:discuss-gnuradio-bounces+marcus.ward=jhuapl....@gnu.org] On Behalf Of Marcus D.
