Well, VideoLAN is first designed to stream on high bandwidth networks.
Therefor, it cannot adapt bitréate on the fly. By default, a stream is
sent "as it is" on the network. You can transode it, using a smaller
bitrate, but this setting will be static.

Well... *very* silly question, but is g++ installed, and in your PATH ?

If bitrate is sufficient and port forwarding enabled, there shouldn't be
any issue.  You couls  also try  to stream over  http, rather  than UDP.
Since the stream  will be pulled by the client,  instead of being pushed
by  the  server,  and  sent  over TCP,  it  should  help  going  through
firewalls.
