Settings – Multi DMZ
Enable
Use this to enable or disable the DMZ setting, as required.
Name
Enter a name to assist you to remember this setting. This name has no effect
on the operation.
For Static IP
Public IP address
Enter the WAN port (Internet) IP address you wish to associate to a PC. This
IP address must have been allocated to you by your ISP.
Private IP
Address (LAN)
Enter the IP address of the PC you wish to associate with this WAN port IP
address. This IP address should be fixed, or reserved. (See the
Host IP
section for details on reserving an IP address.)
For Dynamic IP
WAN
Select the desired WAN port.
Session
•
Select "DHCP" if the IP address on this WAN port is dynamically
assigned. You can only select assign one (1) Private (LAN) IP address to
each port.
•
If using multi-session PPPoE, select the desired PPPoE session. These
sessions are defined on the
Advanced PPPoE
screen. You can assign
one (1) one (1) Private (LAN) IP address to each PPPoE session.
Private IP
Address (LAN)
Enter the IP address of the PC you wish to associate with this WAN port IP
address. This IP address should be fixed, or reserved. (See the
Host IP
section for details on reserving an IP address.)
Access Group
You can decide the users to have the authority of using DMZ, by define the
groups.
Direction
For DMZ, you can allow inbound, outbound only, or both inbound and
outbound both.

UPnP
With UPNP (Universal Plug & Play) function, it can easily setup and configure an entire network,
enable discovery and control of networked devices and services.
Figure 20 UPnP
Settings – UPnP
UPnP Option
If you Enable UPnP, then this two wan router will become one of the entire
local network. You can find out there is an icon show up on network
neighborhood on the window XP OS.
Every time you add a new network device with port mapping, The new
network device will appear on the mapping list.

Advanced Features
This screen allows you to change some advanced settings:
•
NAT
– NAT (Network Address Translation) is the technology which allows a number of LAN PCs
to share one (1) Internet IP address. These settings rarely need to be changed.
•
Remote Access Configuration
– This feature allows you to manage the Load Balancer via the
Internet. You can restrict access to a specified IP address or address range.
•
External Filters Configuration
– These settings determine whether or not the Load Balancer
should respond to ICMP (ping) requests received from the WAN port.
•
Interface Binding
– Use these to ensure that certain traffic is sent by a particular WAN port, and
thereby a particular ISP account. These settings are only useful if using both WAN ports.
Protocol & Port Binding
– This allows you binding WAN1 or WAN2 ports by selecting TCP/UDP
protocol.
Settings – Advanced Features
NAT
Configuration
•
NAT Routing
– NAT (Network Address Translation) is the technology which
allows one (1) WAN (Internet) IP address to be used by many LAN users.
•
If you disable NAT, Internet access is only possible if all PCs are
configured with valid Internet IP addresses. (The Load Balancer needs 2
addresses, 1 for the LAN port, and 1 for the WAN port.)
•
Generally, NAT is disabled only when you wish to use the
Load Balancer
as a Static Router.
•
TCP Timeout
– Enter the desired value to use on both WAN ports. The
default is 300.
•
UDP Timeout
– Enter the desired value to use on both WAN ports. The
default is 120.
•
TCP Window Limit
– Enter the desired value to use on both WAN ports. The
default is 0 (no limit).
•
TCP MSS Limit
– Enter the required MSS (Maximum Segment Size) to use
on both WAN ports. The default is 0 (no limit).,
•
Disable Port Translation
– Enter the desired port range of all packets which
aren’t translated via WAN port.

Session Persistency –
Some Internet applications (notably secure web sites, gaming sites) would need
several established sessions to make a successful transaction (or connection) and most likely they expect
all sessions would be coming from the same source (IP address). Multiple-Wan devices by default
(without any binding rules set) would handle all the traffic using load balance algorithm, sessions would
be distributed and passed over all available wan interfaces and thus when connecting against those
applications or web sites this is breaking its rule (same source) and would create problems (something
like slow connection, web pages not fully loaded etc) . Session binding rule is implemented to avoid such
situation, it indexes all the traffic from each host within LAN side and instruct them going through one
specific (dynamically selected) wan interface during host’s active period and as the result problem is
avoided when communicating with those applications.
a) Enable –
Enable Checkbox will enable Session Persistency mechanism.
b)
Users can use pull-down menu to select TCP, UDP or both protocols for the Internet .
c) Port range –
User an define port number range to decide the traffic sessions, and maintain on that
WAN IP port . For example, if the port range is 2903 ~ 2923, that means only the port number from
2903 to 2923 will keep the sessions accordance for a WAN port.

Remote
Access
Configuration
•
Remote Upgrade
– If enabled, you can use the supplied Windows program to
remotely upgrade the Firmware. If not enabled, upgrades must be performed
by a PC on the LAN.
•
Remote Web-based setup
- – If enabled, access to the Web-based interface
is available via the Internet. (See below for details.) If not enabled, access is
only available to PCs on the LAN.
•
Port
– The port number used when connecting remotely. See below for
details.
•
Allowed IP range
– Remote access is only available to the IP addresses
entered here.
•
Leaving these fields blank will allow access by all PCs.
•
These addresses must be Internet IP addresses, not addresses on the
local LAN.
•
To specify a single address, enter it in both fields.
•
IDENT Port
– Port 113 is associated with the Internet's (Identification /
Authentication) service. When a client program in your computer contacts a
remote server for services such as POP, IMAP, SMTP, that remote server
sends back a query to the "Ident" server running in many systems listening for
these queries on port 113. This means that port 113 is often probed by
attackers as a rich source of your personal information. By default it is
“Disable”.
External
Filters
Configuration
These settings determine whether or not the Load Balancer should respond to
ICMP (ping) requests received from the WAN port.
•
Block Selected packet types
– This acts as "master" switch. If checked, the
selected packet types are blocked. Otherwise, they are accepted.
•
Echo Request, Timestamp Request, …
Select the packet types you wish to
block, using the checkboxes.
Dynamic
Routing
•
RIP v2
– This acts as “master” switch. If enabled, the selected WAN or LAN
will run RIPv1/v2, otherwise they don’t have RIP function.
•
LAN, WAN1, WAN2
– If enabled, any WAN or LAN can execute RIP function.
DNS
Loopback
When you have some servers on LAN and their domain names have already
registered on public DNS. To avoid DNS loop back problem, please enter the
following fields.
•
Domain Name
– Enter the domain name specified by you for local
host/server.
•
Private IP
– Enter the private IP address of your local host/server.
