PCs and other LAN devices become known by these methods:
•
DHCP Client Requests
. By default, the DHCP server in the VPN firewall is enabled,
and will accept and respond to DHCP client requests from PCs and other network
devices. These requests also generate an entry in the database. Because of this,
leaving the DHCP Server feature enabled (on the LAN Setup screen) is strongly
recommended.
•
Scanning the Network
. The local network is scanned using standard methods such
as ARP. The scan will detect active devices that are not DHCP clients. However,
sometimes the name of the PC or device cannot be accurately determined and will be
shown as unknown.
•
Manually Adding Devices
. You can enter information in the
Add Known PCs and
Devices
section and click
Add
to manually add a device to the database.
The
Known PCs and Devices
table lists all current entries in the LAN Groups database. For
each PC or device, the following data is displayed.
Note:
If the network storage is rebooted, the table data is lost until the
network storage rediscovers the devices.
Viewing the DHCP Log
To review the most recent entries in the DHCP log:
1.
Select Network Configuration > LAN Settings from the menu, and then click the
LAN
Setup
tab. The LAN Setup screen is displayed.

IP Address
The current IP address. For DHCP clients, where the IP address is allocated by the
DHCP Server in this device, this IP address will not change. Where the IP address is
set on the PC (as a fixed IP address), you may need to update this entry manually if
the IP address on the PC is changed.
MAC Address
The MAC address of the PC. The MAC address is a low-level network identifier
which is fixed at manufacture.
Group
Each PC or device must be in a single group. The Group column indicates which
group each entry is in. By default, all entries are in the Group1.
