module needs to have the network module enabled so that it can serve IP addresses through the configured network interfaces. The dependencies are shown in the
Depends column and until these are enabled, you can’t enable the module.
The first time you enable a module, you are asked to accept the set of actions that will be carried out and configuration files that will be overwritten. After you have accepted all the actions and listed files, you must save changes in order to apply the configuration.
Confirmation to enable a module Applying the configuration changes
An important feature to consider when working with Zentyal is the way configuration changes are applied when made through the interface. Initially, changes must be accepted in the form, then to make these changes effective and apply them permanently you must click on Save Changes in the top menu. This button will change to red if there are any unsaved changes. Failure to follow this procedure will result in the loss of all changes made during the session once you end it. An exception to this rule is the users and groups management: here the changes are
applied directly.
Save Changes Warning
If you change the network interface configurations, firewall or administrative interface port, you might lose the connection. If this is the case you should change the URL in the browser or reconfigure through the local GUI. General configuration
There are several parameters in the general configuration of Zentyal that can be modified in System ? General.
General configuration
? Password:
You can change the password of a user. It is necessary to introduce
his/her Username, Current password, New password and to confirm the password again in the Change password section. ? Language:
You can change the interface language using Select a language. ? Administrative interface port:
By default, it is the HTTPS port 443, but if you want to use it for the webserver, you must change it to another port and specify it in the URL when you access
https://ip_address:port/.
? Hostname:
It is possible to change the
hostname or the hostname, for example
zentyal.home.lan. The hostname is helpful so the server can be identified from
other hosts in the same network. Location in a Zentyal network
Zentyal can be used in two fundamental ways:
? gateway and firewall for Internet connection, ? server for network (local or Internet) services.
You can decide to install everything on a single host or to separate the different services into several hosts, depending on the requirement characteristics of each deployment.
The image Locations in the network shows the different locations a Zentyal server can take within a network, both working as a link between networks or as a server within the network itself.
Locations in the network
In this documentation you will find out how to configure Zentyal as a gateway and firewall. And of course you will also see how to configure Zentyal when it acts as another server within a network. Network configuration with Zentyal Through
Network ? Interfaces you can access the configuration of each
network card detected by the system and you can select between a static configuration (manually configured), dynamic (DHCP configuration), VLAN (802.1Q)trunk, PPPoE or bridged.
In addition, you can define each interface to be External if it is connected to an external network, such as the Internet, in order to apply stricter firewall policies. If you don’t do this, the interface is considered internal, connected to a local network. When you configure an interface to serve DHCP, not only do you configure the IP
