SIP
Port
(Default
5060)
SIP
uses
a
TCP
port,
as
its
communication
is
bidirectional.
The
SIP
port
is
what
is
used
for
the
connection
protocol,
that
layer
that
initiates
the
two
RTP
streams.
The
SIP
port
must
match
on
both
ends
of
a
connection.
UDP
Port
(Default
9150)
RTP
streams
are
sent
and
received
over
the
UDP
port.
This
port
is
used
for
both
RTP
and
SIP
modes,
as
SIP
negotiates
the
creation
of
RTP
streams.
The
UDP
port
must
match
on
both
ends
of
a
connection.
HTTP
Port
(Default
8080)
The
TCP
port
used
for
HTTP
streaming
only
(normal
web
‐
pages
are
also
served
over
HTTP,
but
these
are
sent
over
port
80,
the
usual
port
to
which
a
web
browser
connects).
A
player
which
supports
HTTP
streams
can
connect
using
the
usual
port
notation
(e.g.
http://www.xxx.yyy.zzz:PORT).
Note
that
prior
to
3.0.1p,
the
Zephyr
Xstream
used
port
8000
for
HTTP
streaming.
TCP
Port
(Default
8800)
This
port
is
currently
unused.
FIREWALLS AND ROUTERS
The
Internet
works
because
there
is
a
central
authority
for
doling
out
IP
addresses.
Any
given
connection
to
the
internet
is
permitted
to
use
some
number
of
designated
addresses
which
can
be
accessed
by
any
machine
that
is
also
connected
to
the
Internet.
Most
connections
are
limited
to
one
IP,
with
many
more
machines
needing
access
to
the
network.
This
is
the
basic
purpose
most
routers.
When
a
device,
such
as
the
Xstream
has
a
"public"
(e.g.
real)
IP
address
it
can
be
directly
accessed
through
a
router.
However,
if
there
is
a
firewall
(which
may
be
built
into
the
router,
or
a
separate
box),
or
a
"private"
IP
address
the
unit
is
not
directly
accessible.
In
these
cases
there
are
a
few
options,
as
outlined
below.
Port
Forwarding
Port
forwarding
is
very
simple.
When
you
have
two
connected
networks,
with
different
numbering
schemes,
they
must
be
connected
by
a
router.
The
machines
on
either
side
of
the
router
cannot
access
each
other.
The
router
itself
can
be
accessed
by
machines
on
either
network,
however.
