ECOTEL 3G 16.1. Revised: 1 March 2011.
7.3.1.2 DNS FORWARDER
With this module, the system can function as a DNS server for the clients in the local network. The system in the
local network sent the DNS query to the ECOTEL.
The advantage is that the clients always enter the ECOTEL’s address as DNS server address, so that no public DNS
server address is required. The ECOTEL functions in this scenario as a router.
Of course, the DNS server’s address can also be transmitted to the clients using the integrated DHCP server. If the
ECOTEL is used as a DSL router or if it sets up a dial-up connection, no entry is required in the
pabx.cfg for the
parameter
NameServer. The DNS server’s address that is negotiated through this connection will be used.
7.3.1.3 IPUPDATE - DYNDNS CLIENT
This function allows you to assign a defined hostname to an IP address that changes dynamically. That means that
you can always reach a device or service through the public IP network, even if, for example, it is a common DSL
connection with dynamic IP address allocation. Several providers support this service.
Make the following entries in the system’s
pabx.cfg, in the [DynDNS] section:
The following software package must be installed:
dnsmasg.tz2 (see
Chapter 7.3.1 ).
The following software package must be installed:
ipupdate.tz2 (see
Chapter 7.3.1 ).
