Chapter 2 enter the number of minutes you want to have elapsed before your Internet connection terminates. The default Max Idle Time is 5 minutes. Keep Alive: Redial Period If you select this option, the Router will periodically check your Internet connection. If you are disconnected, then the Router will automatically re-establish your connection. To use this option, select Keep Alive. In the Redial Period field, you specify how often you want the Router to check the Internet connection. The default Redial Period is 30 seconds. Optional Settings Some of these settings may be required by your ISP. Verify with your ISP before making any changes. Advanced Configuration Router IP Network Address Server Settings (DHCP) The settings allow you to configure the Router's Dynamic Host Configuration Protocol (DHCP) server function. The Router 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 Router's DHCP server option, make sure there is no other DHCP server on your network. Optional Settings Host Name and Domain Name These fields allow you to supply a host and domain name for the Router. Some ISPs, usually cable ISPs, require these names as identification. You may have to check with your ISP to see if your broadband Internet service has been configured with a host and domain name. In most cases, leaving these fields blank will work. MTU MTU is the Maximum Transmission Unit. It specifies the largest packet size permitted for Internet transmission. Select Enable if you want to manually enter the largest packet size that is transmitted. To have the Router select the best MTU for your Internet connection, keep the default setting, Disable. Size When Manual is selected in the MTU field, this option is enabled. Leave this value in the 1200 to 1500 range. The default size depends on the Internet Connection Type: • DHCP, Static IP, or Telstra: 1500 • PPPoE: 1492 • PPTP or L2TP: 1460 Network Setup The Network Setup section changes the settings on the network connected to the Router's Ethernet ports.Wireless setup is performed through the Wireless tab. Router IP This presents both the Router's IP Address and Subnet Mask as seen by your network. EtherFast Cable/DSL Router with 4-Port Switch Network Address Server Settings (DHCP) Local DHCP Server DHCP is enabled by factory default. If you already have a DHCP server on your network, or you don't want a DHCP server, then select Disable (no other DHCP features will be available). Start IP Address Enter a value for the DHCP server to start with when issuing IP addresses. Because the Router's default IP address is 192.168.1.1, the Start IP Address must be 192.168.1.2 or greater, but smaller than 192.168.1.253. The default is 192.168.1.100. Number of Address Enter the maximum number of computers that you want the DHCP server to assign IP addresses to. This number cannot be greater than 253. The default is 50. DHCP Address Range Displayed here is the range of available IP addresses. Client Lease Time The Client Lease Time is the amount of time a network user will be allowed connection to the Router with their current dynamic IP address. Enter the amount of time, in minutes, that the user will be "leased" this dynamic IP address. After the time is up, the user will be automatically assigned a new dynamic IP address. The default is 0 minutes, which means one day. Static DNS 1-3 The Domain Name System (DNS) is how the Internet translates domain or website names into Internet addresses or URLs. Your ISP will provide you with at least one DNS Server IP address. If you wish to use another, enter that IP address in one of these fields. You can enter up to three DNS Server IP addresses here. The Router will use these for quicker access to functioning DNS servers.
