The
Netmask
is 255.255.255.0 by default, and should remain like this except if you know
exactly what you're doing.
The
Gateway
address must be filled if you connect the SB on a network. This is the IP
address of the router.
Same thing for the
Nameserver
. The default is 8.8.8.8 and should work fine.
NOTE:
After you changed the IP address of the SB and clicked Apply, you're not connected
to the SB anymore. You need to enter this new IP address in the address bar of your
Web browser in order to reconnect to the WebUI. Check the LCD of the SB to know
the IP address of the SB.

DDNS
DDNS stands for Dynamic DNS, a method to update a name server in the Domain Name System.
Without going into technical details, DDNS allows you to communicate with a SB that is out in the
field where it does neither have a public (accessible from the WEB) nor a static (not changing) IP
address. The router where the SB is connected to needs a public IP address – this is the case for
most ADSL or cable TV routers you find in private houses. You have to set-up port-forwarding in the
configuration of the router to reach the SB in the network. The DDNS service makes sure that you
can access your SB through a persistent domain name (e.g. mymr.dyndns.org).
Communication with the DDNS service needs an Internet connection – check with the PING
function as described in Section 5.3.10.
For further details, please check the web-site of the DDNS service provider of your choice, the SB
supports the following services:
