It is assumed one IP-gateway at each place (labelled as WEST and EAST). In this
way, the WAN IP address of the router determines the external internet address
of the codec behind this gateway.
„
In order to call from WEST to EAST, the user has to call to the Internet
(or public) IP address of the EAST router: 80.50.50.51. If we try to call to
the local IP address (192.168.1.2), it will be consider a LAN address and
the connection will not succeed.
„
Router NAT configuration: Let all Prodys ports packets pass through and
be forwarded to local IP address of ProntoNet (10.0.0.2 or 192.168.1.2).
Please refer to the user manual of your router; usually you have to look
for “NAT”, “PAT” or “Port Forwarding” description of your network device.
Here follows an example of NAT/NAPT configuration for the labelled as
‘WEST’.
Entry for router First port Last port Local address Map port
Codec West 80 80 10.00.2 80
Codec West 5004 5004 10.00.2 5004
Codec West 5060 5060 10.00.2 5060
Codec West 50011 50039 10.00.2 0
25
Please make sure that for both codecs the default port assignment is provided.
Take into account that this router configuration only applies when the default
25
Map port “0” means for most of the router configuration that the external port number matches
the port number for the local area network. Given an example: an incoming request from the
WAN interface to the port number 50021 will be forwarded to the codec on the same port number
50021.
