This function, with Connect-on-demand selected, will allow the router to connect
any workstation on your LAN to the Internet upon request. If this function is set at
Always-on, no request from the workstation will be needed to connect to the
Internet. If Manual is selected, it will be necessary for the workstation on the LAN
to manually connect to the Internet through this router.

L2TP Connection

If your ISP is using L2TP to provide your Internet connection, the ISP will give you the necessary
information to configure the router.

There are two ways to enable the router to become a L2TP client, one is through assigning the
router an IP address dynamically, which means that the DHCP protocol will be implemented by
the router to automatically configure the IP settings. The user may input the IP settings manually
by choosing the Static IP option above the configuring area.

LAN

You can configure the LAN IP address to suit your preference. Many users will find it convenient
to use the default settings together with DHCP service to manage the IP settings for their private
network. The IP address of the router is the base address used for DHCP. In order to use the
router for DHCP on your LAN, the IP address pool used for DHCP must be compatible with the
IP address of the router. The IP addresses available in the DHCP IP address pool will change
automatically if you change the IP address of the router. See the next section for information on
DHCP setup.

you may also disable the DNS relay and configure hosts on your LAN to use DNS servers
directly. Most users who are using the router for DHCP service on the LAN and are using DNS
servers on the ISP’s network, will leave DNS relay enabled.

DHCP

The DHCP server is enabled by default for the router’s Ethernet LAN interface. DHCP service
will supply IP settings to workstations configured to automatically obtain IP settings that are
connected to the router though the Ethernet port. When the router is used for DHCP it becomes
the default gateway for DHCP client connected to it. The IP address pool can be up to 253 IP
addresses and must be in the subnet of the router’s IP address. The default IP address pool
uses 100 IP addresses in the 192.168.1.100 – 192.168.1.199 range.

DHCP Server for LAN Settings menu

To display the DHCP Server menu, click the DHCP link in the Home directory. Any active DHCP
clients appear in the DHCP Clients List with their IP address and MAC address listed.

The options for DHCP service are as follows:

 Use the router as a DHCP server for your LAN. (DHCP Server Enabled)



Disable DHCP service and manually configure IP settings for workstations.

 Select Static IP Addresses in the subnet for specified devices that do not age out - this

can be used in combination with normal DHCP service.

Static IP Address with DHCP

If the router has the DHCP server enabled it is possible to permanently assign IP addresses to
workstations specified by their MAC address. Up to five IP addresses may be assigned to five
different devices. This will take the chosen IP address used out of the available addresses in the
dynamic IP address pool and give a permanent lease time for the IP address to the selected
device.

LAN) traffic. The Virtual Server function allows remote users to access services on your LAN
such as FTP for file transfers or SMTP and POP3 for e-mail. The router will accept remote
requests for these services at your Global IP Address, using the specified TCP or UDP protocol
and port number, and then redirect these requests to the server on your LAN with the LAN IP
address you specify. Remember that the specified Private IP Address must be within the
useable range of the subnet occupied by the router. Port redirection can also be used to direct
potentially hazardous packets to a proxy server outside your firewall. For example, you can
configure the router to direct HTTP packets to a designated HTTP server in the DMZ.

DMZ

Since some applications are not compatible with NAT, the router supports use of a DMZ IP
address for a single host on the LAN. This IP address is not protected by NAT and will therefore
be visible to agents on the Internet with the right type of software. Keep in mind that any client
PC in the DMZ will be exposed to various types of security risks. If you use the DMZ, take
measures (such as client-based virus protection) to protect the remaining client PCs on your
LAN from possible contamination through the DMZ.
