DNS Settings
The OxyGEN
mini
Office serves as a Domain Name Service (DNS) proxy for all devices on the LAN towards
the DNS servers of the ISP. Normally, the IP addresses of the DNS servers are automatically configured for
every WAN connection (either through PPP or through DHCP), but in certain cases it may be required to
manually configure them.
Figure 7.7: DNS Settings Configuration
Using the
DNS Settings
configuration page it is possible to:
1. Select between:
simultaneous use of the DNS servers obtained by every WAN connection (
All connections
)
use of the DNS servers obtained only by the
Default-route connection
, or
manual configuration of the IP addresses of the DNS servers (
Static servers
)
2. In case of manual DNS configuration, provide the IP address of the primary and
(optional)
secondary DNS servers.
3. Specify the LAN
Domain Name
.
Host Aliases
The DNS servers of the ISP configured through the WAN connections are queried by the OxyGEN
mini
Office for resolving hostnames. In some cases however, it is required that a manual configuration
is performed for some hostname-to-IP bindings.
The
Host Aliases
configuration page enables this
functionality. Following the corresponding link, the following page appears:

At the top of the page, a list of the configured bindings is displayed. You can
Delete
configured
bindings by clicking on the icon
of
Action
column.
In order to make a new static DNS alias, fill in the desired
IP Address
and
Hostname
combination
and finally click
Save
. If the host has already got an IP address automatically through the DHCP server,
the IP Address and Hostname values can be automatically filled in, through the
Host
drop-down list.

Static Routes
The ISP usually provides default-route information through the automatic IP configuration of the WAN
connections. Using specific methods (e.g. dynamic routing protocols or DHCP options), it is also possible
to apply more detailed routing rules on the device. In certain cases, however, manual configuration of
routing entries is required. This functionality is supported through the
Static Routes
configuration page.
Selecting this entry, the following screen appears with a list of the configured static routing entries:

You can
Edit
and

configured route entries by clicking on the icons
and
respectively of

To add a new static routing rule, click

Dynamic Routing
An automatic method of applying routing information on the device, is through the activation of a
dynamic routing protocol, such as RIP. When such a routing protocol is offered by the ISP’s network, use
the
Dynamic Routing
menu entry to activate the corresponding functionality on the OxyGEN
mini
Office.
Figure 7.11: Dynamic Routing
In order to activate RIP on all or a single WAN connection:
1. Select the
Enabled
radio button under
Status
for the overall activation of the dynamic routing
service.
2. Activate or deactivate the protocol for each individual WAN connection, by clicking on the
corresponding
Enabled
or
Disabled
radio button in the table of WAN connections.
3. Click
Apply
