Field IP Address Subnet Mask DHCP Mode Starting IP Address Ending IP Address Primary DNS Server Secondary DNS Server WINS Server Lease Time Relay Gateway Enable DNS Proxy Advanced Configuration Settings Table 4-3. Fields on the DMZ SETUP Page Description DMZ Port Setup Enter the IP address assigned to the wireless controller's DMZ interface. Enter the subnet mask assigned to the wireless controller's DMZ interface. DHCP for DMZ Connected Computers 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. 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. 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. Enter the IP address of the primary DNS server. Enter the IP address of a secondary DNS 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. Enter the duration, in hours, for which IP addresses will be leased to clients. 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 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. 68 DWC-1000 Wireless Controller User's Guide
