10.3.2 Activating DHCP
The Sunny WebBox can obtain its network settings via a DHCP server (Dynamic Host Configuration
Protocol). With this during the start of the Sunny WebBox the IP address, subnet mask, gateway and
DNS server are automatically obtained from the DHCP server.
To detect the Sunny WebBox in your network, you can detect the current network settings via the
SD card (see page 85).
1. Select "WebBox > Settings > Network" in the user interface.
2. Select "Dynamic (DHCP)" in the "Obtain IP address" field.
3. Select [Save].
4. Under "DHCP", select "Yes" in the "Activated" field in order to receive the network settings
dynamically assigned.
5. Select [Save].
☑ The Sunny WebBox obtains the network settings automatically via the DHCP server.
10.3.3 Network Ports
The Sunny WebBox uses four network ports for the various services. If these ports are reserved for
other applications in your network, you can change the ports as follows:
1. In the field "Public virtual HTTP port", enter the port enabled in the router for HTTP access. This
port allows the web server of the Sunny WebBox to be accessed via the Internet.
2. In the "Webserver port" field, enter the port over which the Web server of the Sunny WebBox
can be reached.
Using DHCP
Before setting the Sunny WebBox to dynamic IP address assignment, check your DHCP
server. The DHCP server must extend the lease of the assigned IP address. If the DHCP
server assigns a new IP address after the lease has expired, we do not recommend using
the DHCP server. DHCP servers can normally list all devices to which you have assigned
an IP address. You can now identify the Sunny WebBox based on your MAC address. The
MAC address of your Sunny WebBox is located on the type plate and the "WebBox >
Info" page.
Adjusting the network ports
Test the access to the Sunny WebBox Web server before you change the "Public virtual
HTTP port" setting of the Sunny WebBox. In most cases, the settings do not have to be
changed manually, as the router automatically forwards the queries to the correct ports via
the network. Before adjusting the ports, contact your network administrator.
