30 *anyrtpproxy* is a rtpproxy which can be used in combination with anycast. It uses
31 the same control protocol than rtpproxy though it can be controled through the nathelper
32 plugin of openser. *anyrtpproxy* uses the same synchronisation protocol than *anytun*
33 to sync the session information among all anycast instances.
42 This option instructs *anyrtpproxy* to run in the foreground
43 instead of becoming a daemon.

68 The local interface to listen on for RTP packets

75 -p|--port-range <start> <end>
76 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
78 A pool of ports which should be used by *anyrtpproxy* to relay RTP packets.
79 The range may not overlap between the anycast instances
84 Allow to learn the remote address and port in order to handle clients behind nat.
85 This option should only be enabled if the source is authenticated (i.e. through
91 Disable learning of remote address and port in case the first packet does not
92 come from the client which is specified by openser during configuration. Invoking
93 this parameter increases the security level of the system but in case of nat needs
94 a working nat transversal such as stun.
99 local unicast(sync) port to bind to
101 This port is used by anycast hosts to synchronize information about tunnel
102 endpoints. No payload data is transmitted via this port.
104 It is possible to obtain a list of active connections by telnetting into
105 this port. This port is read-only and unprotected by default. It is advised
106 to protect this port using firewall rules and, eventually, IPsec.
108 -M|--sync-hosts <hostname|ip>:<port>,[<hostname|ip>:<port>[...]]
109 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
111 remote hosts to sync with
113 Here, one has to specify all unicast IP addresses of all
114 other anycast hosts that comprise the anycast tunnel endpoint.
119 Anycast Setup with 3 instances:
120 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
122 On the host with unicast hostname unicast1.anycast.anytun.org and anycast
123 hostname anycast.anytun.org:
124 --------------------------------------------------------------------------------------
125 # anyrtpproxy -i anycast.anytun.org -p 20000 25000 -S 2342 \
126 -M unicast2.anycast.anytun.org:2342,unicast3.anycast.anytun.org:2342
127 --------------------------------------------------------------------------------------
129 On the host with unicast hostname unicast2.anycast.anytun.org and anycast
130 hostname anycast.anytun.org:
131 --------------------------------------------------------------------------------------
132 # anyrtpproxy -i anycast.anytun.org -p 25000 30000 -S 2342 \
133 -M unicast1.anycast.anytun.org:2342,unicast3.anycast.anytun.org:2342
134 --------------------------------------------------------------------------------------
136 On the host with unicast hostname unicast3.anycast.anytun.org and anycast
137 hostname anycast.anytun.org:
138 --------------------------------------------------------------------------------------
139 # anyrtpproxy -i anycast.anytun.org -p 30000 35000 -S 2342 \
140 -M unicast1.anycast.anytun.org:2342,unicast2.anycast.anytun.org:2342

148 Most likely there are some bugs in *anyrtpproxy*. If you find a bug, please let
149 the developers know at satp@anytun.org. Of course, patches are preferred.
