Wake On LAN
Most modern PCs have a special capability of being automatically activated while in
Off (Standby)
status, when they receive a special Ethernet packet. This capability is called Wake On LAN (WOL) and
can be used for the remote activation of PCs or servers without physical access to their
On/Off
switch.
Figure 7.12: Host wake on LAN
In order to activate a host on the LAN using the Wake On LAN service, enter the
MAC
address of
the host and click
Apply
. Alternatively, if the host has already been added to the DHCP server’s list of
static leases, the MAC address can be automatically filled in, through the
Host
drop-down list.
Note
The support of the Wake On LAN service by the PC or server depends on its BIOS and
Network Interface Card (NIC) settings.

Public IPs
In the majority of installations, each host in the LAN uses a separate private IP address and accesses the
Internet through the automatic transformation by the OxyGEN
mini
Office between the private and one
or more public IP addresses (NAT operation). In some cases, however, it is required to use also public IP
addresses in the LAN (usually for Web servers, FTP servers etc.). In order to realize this, one option is to use
a separate DMZ (DeMilitarized Zone) Interface Group, totally separated from the other LAN hosts (refer
to section
Addresses
on page 71). If it required, however, that the hosts with the public IP addresses
coexist in the same Ethernet segment with the other internal hosts using private IP addresses, a second
available option is to notify the OxyGEN
mini
Office about the existance of public IPs in the LAN. This is
achieved through the
Public IPs
configuration menu. In this configuration page, a subnet of public IP
addresses can be configured for each Interface Group. IP addresses belonging to these subnets will be
routed directly (without NAT), and NAT will only be applied to the private IP addresses.
Figure 7.13: Public IP Addresses
Using the corresponding table entries, for each local LAN Interface Group:
1. Enter the public
IP Address
used for the OxyGEN
mini
Office. This will be used by the device as a
secondary IP and it must be configured on each host in the LAN using a public IP as the default
gateway.
2. Enter the
Netmask
of the public IP subnet.
The value of this parameter together with the
corresponding
IP Address
define the subnet of IPs that will not be treated as public by the OxyGEN
mini
Office and will not be translated via NAT.
3. Select if the subnet of public IPs is going to be protected with firewall or not, using the
Firewalled
checkbox.
4. Check the
Enabled
checkbox in order to activate the relevant operation for the specific Interface
Group.
5. Click
Apply
.

Configuration
This page allows the configuration of all the general parameters controling the operation of your wireless
connection:
Figure 8.1: Wireless Settings
To configure the wireless network:
1.
Enable
or
Disable
the wireless network using the corresponding
Status
radio button
2. Assign a wireless
Network name
(SSID)
3. Choose if the SSID value is going to be broadcast and visible (
On
) or hidden (
Off
) using the radio
buttons of
Broadcast SSID
4. Select the used wireless frequency channel as
Auto
or specify a specific channel number
5. Select the required
Transmit power level
6. Optionally set the
Beacon interval
. The default setting of 100 milliseconds should be ideal for most
situations.
7. Select the
Mode
of operation between any combination of the supported 802.11 profiles.
8. Select the desirable
Bandwidth
of operation for the selected
Mode
.
9. Choose whether
WMM
(Wi-Fi Multimedia Extensions) should be enabled or not.

Security
This page allows the modification of the wireless security settings.
Select the desired security option from the drop-down list next to the
Security mode
label.
The
available security options are:
WEP
,
WPA
and
WPA2
. Entry
Off
leaves your wireless traffic unencrypted.
WARNING
If no encryption is used (Off mode), anyone within the range of the wireless network can
potentially capture your Internet traffic and access your home network.
WEP Encryption
Wired Equivalent Privacy (WEP) is a widely used, but deprecated wireless security method because of
the deficiencies found in its encryption algorithm.
Figure 8.2: Wireless Security - WEP
To activate WEP security mode:
1. Select
WEP
from the
Security mode
drop-down list.
2. Choose between
64-bit
or
128-bit
security key lengths.
3. Enter a security
WEP key
of 5 or 13 ASCII characters respectively.
4. Click
Apply
.
