On the other hand, when establishing a connection between Codecs, the
IP addresses to call, will be the public (WAN) address of the
corresponding routers.
Also, user has to keep in mind that some new Operating Systems like XP
Home SP2 comes fitted with a firewall enabled by default. This
firewall
might be configured to disable incoming traffic, thus not allowing
connection to the web page
.
V.6.16
Examples of port setup for calling over IP
This chapter is aimed at providing a fundamental understanding of TCP/UDP port
configuration for those scenarios where a router/firewall with NAT (Network
Address Translation) requires the configuration (open/forwarding) of the
incoming traffic based on the TCP/UDP port number in the router.
Prodys is ahead of the development of the current standard from the EBU group
for audio distribution over IP, although we also support our own proprietary
protocols for those cases where they better suit customer needs. Therefore, this
chapter comprises both, configuration for Prodys Proprietary Protocols and for
SIP/SAP/SDP/RTP protocols (complying to EBU Tech 3326 standard)
24
. From now
on we will use only SIP to refer to all protocols included in this standard.
V.6.16.1.
Different network topologies and port configuration
This chapter describes how to configure and operate with Prodys IP codecs when
making IP connections for different network topologies.
The following picture depicts a complex network where star topology and array
configuration have been merged.
•
If only one single codec behind a router/gateway is to connect, you might
refer to the “One-to-One topology” chapter below.
•
If multiple codecs are deployed sharing the same gateway (e.g. Nereus or
several ProntoNets on one site), the configuration description in “Array of
24
SIP is the commercial name commonly adopted to refer to the EBU standard for audio over IP.
This standard also comprises other protocols such us SAP, SDP and RTP.
