Manual
Version 1.2.0, valid from FW Version 03.01.07(13)
Not all parameters can be set in the WBM. If you want to set other values for the
existing parameters or want to pass other parameters via DHCP, the DHCP
server must be manually configured. For the controller, the DHCP server service
is handled by the program "dnsmasq".
From a Linux
®
command line, an editor must be used to change the file
“/etc/dnsmasq.d/dnsmasq_default.conf” to set the configuration.
4.1.5.3 DNS Server
The controller offers the DNS server service for the automatic assignment of
hostnames to IP addresses of network stations.
The DNS server takes over the names and IP addresses of local network stations
from the DHCP server. This DNS server routes requests for non-local names,
such as from the Internet, to higher-level DNS servers if configured and
accessible.
The following settings are possible for the DNS server:
•
The service itself (enabled/disabled)
•
Access type to the assignments
The requests are buffered in “Proxy” mode (throughput optimized).
In Relay mode the requests are routed directly to higher-level name
servers.
•
A list with up to 15 static assignments of IP addresses to hostnames
If only the hostname is used, the configured or default domain is added to
the hostname automatically to ensure FQDN name resolution.
The settings are made, e.g., in the WBM, via the “Configuration of DNS Service”
page.
