Server Services
10.10.1
Setting up DNS Forwarding
You may use the MLR 3G 2.0 as DNS relay server. When the MLR 3G 2.0 is configured as
DNS server at the locally connected network devices, the MLR 3G 2.0 will either forward
the DNS queries to the previously configured DNS servers in the Internet, or will use the
IP addresses sent during the PPP connection setup as DNS server.
Configuration with the web interface
DNS servers can be transferred to the MLR 3G 2.0 during PPP connection es-
tablishment. For the MLR 3G 2.0 to be able to forward the DNS queries to
de-
fined name servers
, enter the addresses of the according name servers in the
entry fields "First DNS server address" and "Second DNS server address".
Save your settings
by clicking "OK".
10.10.2
Setting up the Dynamic DNS Update
The MLR 3G 2.0 can forward the IP address, which it was allocated during the dial-in into
the Internet, to a DynDNS provider, so it can be reached from the Internet with a domain
name. This means that the network behind the MLR 3G 2.0 can always be reached with
the same domain name from the Internet, also for dynamically allocated IP addresses (if
the allocated IP address for incoming connections is not protected). The MLR 3G 2.0 will
update the IP address connected to the domain name at the DynDNS provider during
each dialup. For this function, you will need an account with a DynDNS provider.
A public IP address must also be provided from the provider for packet-
based wireless connections (GPRS/EDGE/UMTS/HSDPA). Otherwise, the de-
vice cannot be accessed despite this service.
Configuration with the web interface
In order to
configure the dynamic DNS update
, check in the menu "Server ser-
vices" on the page "Dyn. DNS update" the checkbox "Activate dynamic DNS
update".
Select a
DynDNS provider
from the drop-down menu "DynDNS provider".
In order to
define an own DynDNS server
, select in the drop-down menu
"DynDNS provider" the entry "Userdefined DynDNS" and enter a DynDNS
server in the entry field "Userdefined DynDNS server".
Enter the
domain name to be updated
into the entry field "Domain name".
Enter the
user name and password
of your DynDNS account into the entry
fields "User name" and "Password".
Save your settings
by clicking "OK".
