11 Appendix A: Basic Network Server(s) Configuration
In this chapter, we describe how to setup the various server elements in the system.
11.1 Server setup
In the network, the server environment is installed as a centralized system.
The main server types hosted on the network include SIP, DNS/DHCP and HTTP/TFTP Servers. These servers can be
hosted both in one or multiple windows and/or Linux Server environment.
Management servers are normally installed to monitor and manage the network in detail. Each Base-station status
can be checked. Each Subscriber Terminal can be monitored over the air from a centralized location.
Further, new software can be uploaded to all system elements from the centralized location (typically a TFTP server)
on an individual basis. This includes Subscriber Handsets where the latest software is downloaded over the air.
11.2 Requirements
Regardless of whether you will be installing a centrally provisioned system, you must perform basic TCP/IP network
setup, such as IP address and subnet mask configuration, to get your organization’s phones up and running.
11.3 DNS Server Installation/Setup
Name server is a name server service installed in a server for mapping or resolution of humanly memorable domain
names and hostnames into the corresponding numeric Internet Protocol (IP) addresses.
The customer should refer to the platform vendor either windows or Linux vendor for detail step-by-step guide on
how to install and configure Domain Name System for internet access. In this section, we briefly describe hints on how
to setup DNS behind NAT or Firewall.
11.3.1.1 Hints on how to Configure DNS behind a Firewall/NAT
Proxy and Network Address Translation (NAT) devices can restrict access to ports. Set the DNS to use UDP port 53 and
TCP port 53. For windows Servers, set the RCP option on the DNS Service Management console and configure the RCP
to use port 135.
These settings should be enough to resolve some of potential issues that may occur when you configure DNS and
firewalls/NAT.
