Network Configuration |
 |
|
DMZ Setup |
The De-Militarized Zone (DMZ) is a network which, when compared to the LAN, has
fewer firewall restrictions, by default. This zone can be used to host servers
and give public access to them. Port 8 on the LAN of the router can be dedicated
as a hardware DMZ port and safely provide the Internet services without
compromising security on your LAN. |
DMZ Port Setup |
The DMZ Port is not enabled by default. To enable it, select the
Yes radio box under the
Do you want to enable DMZ Port? option. |
Type the IP address and subnet mask for the DMZ port in the respective
IP Address and
Subnet Mask fields. |
Note: The IP subnet of the DMZ should be different
from that of the LAN port and the WAN port(s).
Example:
WAN 1: 10.0.0.1 with subnet 255.0.0.0
WAN2: 20.0.0.1 with subnet 255.0.0.0
LAN: 192.168.1.1 with subnet 255.255.255.0
DMZ: 192.168.10.1 with subnet 255.255.255.0 |
DHCP for DMZ Connected Computers |
If the computers on the DMZ network are configured with static IP addresses or
configured to use another DHCP server, select the Disable DHCP option. |
To use the router as a DHCP server, select
DHCP Server and configure the following items: |
Domain Name: Name of the domain (Optional) |
Starting IP Address: First IP address in the range.
Any new DHCP client joining the DMZ network will be assigned an IP address
between this address and the Ending IP Address. |
Ending IP Address: Last IP address in the range.
Any new DHCP client joining the DMZ network will be assigned an IP address
between the
Starting IP Address and this IP address. |
Note: The Starting and Ending DHCP addresses should
be in the same “network” as the DMZ port TCP/IP address of the router (the IP
Address field in DMZ TCP/IP Setup section). |
Primary DNS Server: primary DNS Server IP. |
Secondary DNS Server: Secondary DNS Server IP. |
WINS Server: IP address of a WINS server
(Optional). The Windows Internet Naming Service (WINS) is the equivalent of a
DNS server but uses the NetBIOS protocol to resolve hostnames. If the network
consists only of Windows based computers and you want to use a WINS server
for name resolution, then enter the IP address of the WINS server. The router
will include the WINS server IP address in the DHCP configuration when
acknowledging a DHCP request from a DHCP client. |
Lease Time: Duration (in hours) for which an IP
address will be leased. |
Enable DNS Proxy: Check the
Enable radio box to configure the router as a DNS server
for the LAN. The router will act as a proxy for all DNS requests and communicate
with the ISP’s DNS servers (as configured on the WAN Settings page). When
disabled, all DHCP clients receive the DNS IP addresses of the ISP. The feature
is particularly useful in Auto Rollover mode. For example, if the DNS servers
for each connection are different, then a link failure may render the DNS
servers inaccessible. But when DNS proxy is enabled, clients make requests to
the router and the router, in turn, sends those requests to the DNS servers of
the active connection. |
Click
Apply to save the settings. The DMZ LED on LAN port
8 will light up to indicate that the DMZ port has been enabled. |
Click
Reset to revert to the
previous settings. |
