Table 4-3. Fields on the DMZ SETUP Page
Field Description
DMZ Port Setup
IP Address Enter the IP address assigned to the wireless controller’s DMZ interface.
Subnet Mask Enter the subnet mask assigned to the wireless controller’s DMZ interface.
DHCP for DMZ Connected Computers
DHCP Mode Select a DHCP mode for the DMZ. Choices are:
• None = select this setting if the computers on the DMZ are configured with static IP addresses
or are configured to use another DHCP server. The remaining fields become unavailable.
• DHCP Server = select this setting to use the wireless controller as a DHCP server. Complete
the remaining settings on the page.
• DHCP Relay = if you select this setting, you need only enter the relay gateway information.
Starting IP Address Enter the first IP address in the range. Any new DHCP client joining the LAN will be assigned an
IP address between this address and the Ending IP Address. The Starting IP addresses should
be in the same network as the LAN TCP/IP address of the wireless controller.
Ending IP Address Enter the last IP address in the range. Any new DHCP client joining the LAN will be assigned an
IP address between this address and the Ending IP Address. The Ending IP addresses should
be in the same network as the LAN TCP/IP address of the wireless controller.
Primary DNS Server Enter the IP address of the primary DNS server.
Secondary DNS Server Enter the IP address of a secondary DNS server.
WINS Server (Optional) Windows Internet Naming Service (WINS) is equivalent to 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, 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 Enter the duration, in hours, for which IP addresses will be leased to clients.
Relay Gateway Enter the gateway address. This is the only configuration parameter required in this section when
DHCP Relay is selected as its DHCP mode.
DMZ Proxy
Enable DNS Proxy Enables or disables DNS proxy on this LAN. Choices are:
• Checked = enable DNS proxy on this LAN. The wireless controller acts as a proxy for all DNS
requests and communicates with the ISP's DNS servers (as configured in the Option settings
page). All DHCP clients receive the Primary/Secondary DNS IP along with the IP address,
where the DNS Proxy is running, i.e. the box's LAN IP. All DHCP clients receive the DNS IP
addresses of the ISP, excluding the DNS Proxy IP address when it is disabled. The feature is
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. However, when the
DNS proxy is enabled, then clients can make requests to the wireless controller and the
controller, in turn, sends those requests to the DNS servers of the active connection.
• Unchecked = disable DNS proxy on this LAN.
