Addresses

Each of the Interface Groups supporting the different services has its own private (LAN) IP address. The

Addresses

configuration menu allows the modification of this IP address for each Interface Group.

Figure 7.2: LAN Addresses

To configure the LAN IP address of a broadband service:

1. Make sure that the

Enabled

checkbox is checked

2. Enter the

IP Address

. For example, enter

192.168.1.254

3. Enter the

Netmask

. For example, enter

255.255.255.0

4. Click

Apply

.

Alternatively, you can use a DHCP client for automatic configuration of the LAN IP address of the

OxyGEN

mini

Office. Enable/Disable the DHCP client by selecting/deselecting the corresponding

DHCP

Client

checkbox.

Note

The default LAN IP address for the Data Interface Group is 192.168.1.254.

IPv6 Addresses

In IPv6-enabled products you can enable or disable the IPv6 functionality of the OxyGEN

mini

Office by

using the respective radio button that appears under IPv6 addresses. Note that enabling the generic

IPv6 functionality is necessary in order for subsection

IPv6 Options

to appear in page

62

.

Moreover, through the

Status

drop-down list, you can choose between

Off

,

Fixed

and

Auto

states for

each Interface Group. This option refers to the Unique Local Address (ULA) configuration. When option

Auto

is selected, a ULA address is configured for the respective interface based on a pseudo-random

Gennet s.a.

algorithm that combines NTP time and the so-called EUI-64 identifier according to RFC 4193. Otherwise,

you may choose the

Fixed

mode of operation, where the administrator may define their own ULA format

by inserting the corresponding entries in the

Address

and

Mask

fields.

Finally, you can disable ULA

addresses by selecting

Off

option for the respective Interface Group.

DHCP

The embedded DHCP server of the OxyGEN

mini

Office allows the automatic network configuration of

all LAN devices on each Interface Group.

Figure 7.4: DHCP Server Configuration

To configure the DHCP Server:

1. Enable/Disable the DHCP server by selecting

On/Off

from the drop-down menu of

Status

column.

The status of the DHCP sever is changed accordingly. A third option is

Relay

, where the local

DHCP server is deactivated and all DHCP requests received on the LAN are forwarded to an

external DHCP server.

2. Specify the IP Address range by entering the

Start IP

and

End IP

values. In case of

Relay

operation,

only the

Start IP

entry field is active and must contain the IP address of the external DHCP server.

3. Configure the validity period of each assigned IP address under the

Lease Time

parameter. The

default lease time value is

86400

seconds (1 day).

4. Click

Apply

.

Note

By default the DHCP server is activated only for the Data Interface Group with an

address pool from 192.168.1.51 to 192.168.1.100.

Static DHCP Leases

The embedded DHCP server of the OxyGEN

mini

Office assigns IP settings to every device on each

Interface Group using the available addresses from the corresponding address pool in a dynamic way.

Gennet s.a.

Administrator’s Guide

In some cases, however (e.g. port forwarding), it is required that a PC or some other network device

will always obtain the same IP address. In this case, the DHCP server is required to assign a fixed IP

address based on the physical (MAC) address of the device. The

Static DHCP Leases

configuration

page enables this functionality. Following the corresponding link, the following page appears:

Figure 7.5: Static DHCP Leases

At the top of the page, a list of the configured address reservations is displayed. You can

Delete

configured reservations by clicking on the icon

of

Action

column.

In order to make a new static DHCP lease, fill in the

MAC

address of the device along with the

desired

IP Address

and

Hostname

(optional)

and finally click

Save

. If the host has already got an IP

address automatically through the DHCP server, the MAC, IP Address and Hostname values can be

automatically filled in, through the

Host

drop-down list.

LAN IPv6 Addresses

For IPv6 enabled products, a second menu appears, entitled

LAN IPv6 addresses

. Here, you can specify

the method of IPv6 addressing to the LAN hosts.

In particular, for each Interface Group there is a

possibility of different options.

1. Stateless Address Configuration (SLAAC) method may be used for LAN addressing. To enable

this method,

Router Advertisements

(

RAs

) must be enabled by selecting option

On

in the

corresponding drop-down list.

With this option, Router Advertisements that contain Prefix and

LifeTime information are sent to the LAN hosts that belong to the specific Interface Group.

Moreover, RDNSS option is enabled, which means that supporting hosts may obtain DNS server

information as well.

If RAs are desirable but RDNSS option is not required, you may choose

option

On(no DNS)

. Finally, option

Off

disables router advertisements. Moreover, in the

Router

Gennet s.a.

OxyGEN

Administrator’s Guide

Advertisements

part of the page, detailed parameters, such as the

Maximum RA interval

,

Valid

and

Preferred Lifetime

may be configured (in seconds). Default values for these parameters are

600 secs, 86400 and 14400 secs respectively.

2. Stateless/Stateful

DHCPv6

method may be used. When

DHCPv6

drop-down list is set to

On

and

RA

option is enabled, the Router Advertisement packets have the so-called Other Configuration

Flag set to 1. Subsequently, the LAN host is dictated to start a DHCPv6 request and the OxyGEN

mini

Office provides it with stateless configuration parameters, such as DNS server, NTP, SIP servers,

AFTR server etc. If

DHCPv6

is

On

and

RA

option is

Off

, the Router Advertisement packets have

both Managed and Other Configuration Flags set to 1, which means that both prefix information

and stateless information are transmitted over DHCPv6. Finally, when

DHCPv6

is enabled, you may

choose whether the device will automatically assign the /64 prefixes to the LAN hosts derived from

the WAN-side obtained prefix (this may be done by selecting

Auto

from the list) or may be done

manually by selecting

Manual

and inserting the desired /64 subnet in the

Subnet

box. Finally, in

the

Manual

mode, you may also configure the

Lease

in seconds for each Interface Group.
