Setup Local Network Help

Setup Tab / Local Network Setup

Configure the Gateway's Local Area Network (LAN) settings on this screen. There are two views available, Basic and Advanced. The default view is Basic. To display the Advanced View, click Advanced View. To return to the Basic View, click Basic View.
The Local Network section changes the settings on the network connected to the Gateway's Ethernet ports. Wireless setup is performed through the Wireless tab.

Local Network
Gateway IP	The values for the Gateway's local IP Address and Subnet Mask are displayed. In most cases, keeping the default values will work. IP Address The default value is 192.168.1.1. Subnet Mask The default value is 255.255.255.0.
Network Address Server Settings (DHCP)	The settings allow you to configure the Gateway's Dynamic Host Configuration Protocol (DHCP) server function. The Gateway can be used as a DHCP server for your network. A DHCP server automatically assigns an IP address to each computer on your network. If you choose to enable the Gateway's DHCP server option, make sure there is no other DHCP server on your network. DHCP Server A Dynamic Host Configuration Protocol (DHCP) server automatically assigns an IP address to each computer on your network for you. Unless you already have one, Linksys recommends that you keep the default, Enable. Click the DHCP Options button to DHCP Options setup screen (if DHCP Server is enabled) or the Conditional Serving button to Conditional Serving Pool setup screen (if DHCP Server is enabled). IP Pool Start Starting DHCP Pool IP IP Pool End Ending DHCP Pool IP Client Lease Time The Client Lease Time is the amount of time a network device will be allowed connection to the Gateway with its current dynamic IP address. Enter the number of minutes that the device will be "leased" this dynamic IP address. After the time is up, the device will be automatically assigned a new dynamic IP address. The default is 1440 minutes. DNS Proxy (Advanced View) The Domain Name System (DNS) is how the Internet translates domain or website names into Internet addresses or URLs. To use DNS Proxy, keep the default, Enabled. Otherwise, select Disabled. Static DNS 1-3 (Advanced View) These entries are valid only when the DNS Proxy option is disabled. At least one DNS server IP address is provided by your service provider. You can enter up to three DNS server IP addresses here. The Gateway will use these for quicker access to functioning DNS servers. WINS (Advanced View) The Windows Internet Naming Service (WINS) converts NetBIOS names to IP addresses. If you use a WINS server, enter that server's IP address here. Otherwise, leave this field blank. Domain Name (Advanced View) Enter the Domain Name of your local network. Reserved IP List (Advanced View) Enter the IP addresses you want to reserve, so they will not be leased to DHCP clients.
Static Mapping (Advanced View)	Enter up to ten static mapping rules. MAC Address Enter the MAC address of the local network device. IP Address Enter the local IP address you want the device to use.
Advanced DHCP Settings (Advanced View)	DHCP Address This option defines the DHCP address allocation method. To assign local IP addresses from the DHCP pool you have defined, keep the default, Use DHCP Pool. To have the local network devices share the WAN subnet address, select Use WAN Subnet. In this passthrough mode, the local computers get WAN-side IP addresses. They bypass NAT and are visible on the service provider's network. However, these computers can still communicate with other computers that are allocated private IP addresses. To have a local network device share the WAN IP address, select Share WAN IP. In this mode, which is also known as super-DMZ mode, a single computer bypasses NAT. You can specify the computer's MAC address in the MAC Address field. WAN IP Interface If you selected Use WAN Subnet or Share WAN IP, select the appropriate WAN IP connection to use. MAC Address If you selected Share WAN IP, enter the MAC address of the local network device. Lease Time Enter the number of seconds you want the local network device to lease the WAN IP address.
Time Settings (Advanced View)	Time Zone Select the time zone in which your network functions. Automatically adjust clock for daylight saving changes Select this option if you want the Gateway to automatically adjust for daylight saving time. Note that some time zones do not have daylight saving, in this case this checkbox is greyed out. NTP Server 1/2 Enter the URL (web address) of the Network Time Protocol (NTP) server you want to use. The default NTP servers are time.nist.gov and clock.isc.org. Click the Update Time button to synchronize with NTP servers immediately.
