\ejabberd{} is able to act as a stand-alone STUN server
(\footahref{http://tools.ietf.org/html/rfc5389}{RFC 5389}). Currently only Binding usage
is supported. In that role \ejabberd{} helps clients with Jingle ICE (\xepref{0176}) support to discover their external addresses and ports.
You should configure \term{ejabberd\_stun} listening module as described in \ref{listened} section.
If \option{certfile} option is defined, \ejabberd{} multiplexes TCP and
TLS over TCP connections on the same port. Obviously, \option{certfile} option
is defined for \term{tcp} only. Note however that TCP or TLS over TCP
support is not required for Binding usage and is reserved for
\footahref{http://tools.ietf.org/html/draft-ietf-behave-turn-16}{TURN}
functionality. Feel free to configure \term{udp} transport only.

{5349, ejabberd_stun, [{certfile, "/etc/ejabberd/server.pem"}]},

You also need to configure DNS SRV records properly so clients can easily discover a
STUN server serving your XMPP domain. Refer to section

of \footahref{http://tools.ietf.org/html/rfc5389}{RFC 5389} for details.
