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

and

configured route entries by clicking on the icons

and

respectively of

To add a new static routing rule, click

WARNING

Enter static routing entries with caution!

Wrong routing rules can lead to loss of

connectivity or degradation of service.

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
