This Chapter explains the settings available via the Advanced configuration section of the "Advanced" menu.
Normally, it is not necessary to use these screens, or change any settings. These screens and settings are provided to deal with non-standard situations, or to provide additional options for advanced users.
The settings available are:
PC Database
|
This is the list of PCs shown when you select the "DMZ PC" or a "Virtual
Server". This database is maintained automatically, but you can add and delete
entries for PCs which use a Fixed (Static) IP Address.
|
Options
|
Enable or Disable various options.
|
Printer Port
|
Configure the Printer port for use with AppleTalk or Unix. (For Windows, no
configuration is required or possible.)
|
MAC Address
|
Set the MAC (hardware) address used on the Internet (WAN port) interface.
This is required only if your ISP has recorded the MAC (hardware) address you
should use.
|
Routing
|
Only required if your LAN has other Routers or Gateways.
|
The PC Database is used whenever you need to select a PC (e.g. for the "DMZ" PC). It eliminates the need to enter IP addresses. An example PC Database screen is shown below.
PC Database |
|
PCs
|
This lists all current entries. Data displayed is name (IP Address)
type. The "type" indicates whether the PC is connected to the LAN or WLAN
(Wireless LAN).
|
Name
|
If adding a new PC to the list, enter its name here. It is best if this
matches the PC's "hostname".
|
IP Address
|
Enter the IP Address of the PC. The PC will be sent a "ping" to determine
its hardware address. If the PC is not available (not connected, or not powered
On) you will not be able to add it.
|
Buttons |
|
This will add the new PC to the list. The PC will be sent a "ping" to
determine its hardware address. If the PC is not available (not connected, or
not powered On) you will not be able to add it.
|
|
Delete
|
Delete the selected PC from the list. This should be done in 2
situations:
|
Refresh
|
Update the data on screen.
|
Generate Report
|
Display a read-only list showing full details of all entries in the PC
database.
|
This screen allows advanced users to enter or change a number of settings. For normal operation, there is no need to use this screen or change any settings.
An example Options screen is shown below.
Backup DNS |
|
IP Address
|
Enter the IP Address of the DNS (Domain Name Servers) here. These DNS will
be used only if the primary DNS is unavailable.
|
TFTP |
|
Enable Firmware Upgrade using TFTP
|
|
UPnP |
|
Enable UPnP
Services |
|
Allow Configuration...
|
|
Allow Internet access to be disabled
|
|
Firewall |
|
Enable DoS
Firewall |
If enabled, DoS (Denial of Service) attacks will be detected and blocked.
The default is enabled. It is strongly recommended that this setting be left
enabled.
Note:
|
Threshold
|
This setting affects the number of "half-open" connections allowed.
|
Normally, these settings do not need to be changed.
Figure 46: Printer Port Screen
AppleTalk |
|
AppleTalk zone
|
This determines which Apple systems can gain access to this printer. The
default value is *, which allows access by all systems. If you enter another
zone name, only Apple systems in that zone will be able to access the
printer.
|
Printer Object Type
|
Sets the type of printer attached. The default setting is "LaserWriter".
If the "Printer Object Type" is incorrect, the printer will not be visible
from your Apple system.
|
Communication
Protocol |
You must use the same setting as your Macintosh.
|
Logical Printers |
|
No (L1, L2, L3)
|
Logical printer configuration is only required if using LPD printing under
Linux or Unix. Otherwise, these settings are ignored
There are 3 Logical Printers (Ports), named L1, L2, and L3.
These names cannot be changed, and must be used when selecting the logical
printer from your Unix system.
|
Pre-string (HEX)
|
Enter (in HEX) the series of printer commands to be sent to the attached
printer BEFORE each print job.
|
Post-string (HEX)
|
Enter (in HEX) the series of printer commands to be sent to the attached
printer AFTER each print job.
|
LF to CR/LF
|
If checked, Unix-style LF (line feed) characters at the end of each line
will be converted to CR/LF (carriage return/line feed) pairs, as used in MSDOS
and Windows.
|
The MAC (hardware) address is a low-level network identifier. It may be called "MAC Address", "Hardware Address", or "Physical Address". On a PC, this address is associated with the Network card or adapter. The address on the MAC Address screen is the address on the Internet (WAN port) interface, and has no effect on the LAN interface.
Select MAC Address from the Advanced menu to reach a screen like the example below.
MAC (hardware) Address
|
The current MAC (hardware) address is displayed.
If your ISP has recorded a Hardware Address, you can "spoof" that address
by entering it in the address field. The hardware address consists of 12
characters, where each character is a digit (0..9) or a character between A and
F.
|
Buttons |
|
Default
|
Inserts the default MAC address into the MAC address field. You must click
"Save" to actually change the address used.
|
Copy from PC
|
Inserts the MAC address from your PC into the MAC address field. You must
click "Save" to actually change the address used.
|
Save
|
Save your changes to the LevelOne Wireless Broadband Router.
|
Cancel
|
Reverse any changes made since the last "Save".
|
![]() |
If the MAC address is changed, the LevelOne Wireless Broadband Router must restart. |
The routing table is accessed by the Routing link on the Advanced screen.
Generally, you will use either RIP (Routing Information Protocol) OR the Static Routing Table, as explained above, although is it possible to use both methods simultaneously.
Static Routing Table

It is essential that all IP packets for devices not on the local LAN be passed to the LevelOne Wireless Broadband Router , so that they can be forwarded to the external LAN, WAN, or Internet. To achieve this, the local LAN must be configured to use the LevelOne Wireless Broadband Router as the Default Route or Default Gateway.
The local router is the Router installed on the same LAN segment as the LevelOne Wireless Broadband Router. This router requires that the Default Route is the LevelOne Wireless Broadband Router itself. Typically, routers have a special entry for the Default Route. It should be configured as follows.
Destination IP Address
|
Normally 0.0.0.0, but check your router documentation.
|
Network Mask
|
Normally 0.0.0.0, but check your router documentation.
|
Gateway IP Address
|
The IP Address of the LevelOne Wireless Broadband Router.
|
Metric
|

|
Other routers on the local LAN must use the LevelOne Wireless Broadband Router 's Local Router as the Default Route. The entries will be the same as the LevelOne Wireless Broadband Router 's local router, with the exception of the Gateway IP Address.
For the LAN shown above, with 2 routers and 3 LAN segments, the LevelOne Wireless Broadband Router requires 2 entries as follows.
