ADSL2/2+ Ethernet/USB Router User Guide

•IP Address: Enter the Router’s local IP Address, then you can access to the Web-based Utility via the IP Address, the default value is 192.168.1.1.

•IP Subnet Mask: Enter the Router’s Subnet Mask, the default value is 255.255.255.0.

•Dynamic Route: Select this option to specify the RIP (Routing Information protocol) version for LAN interface, including RIP1, RIP2-Band RIP2-M. RIP2-B and RIP2-M are both sent in RIP-2 format, the difference is that RIP2-M using Multicast, while RIP2-B using Broadcast format.

•Direction: Select this option to specify the RIP direction. None is for disabling the RIP function. Both means the ADSL Router will periodically send routing information and accept routing information, and then incorporate them into routing table. IN only means the ADLS router will only accept but will not send RIP packet. OUT only means the ADLS router will only send but will not accept RIP packet.

•Multicast: Select IGMP version, or disable the function. IGMP (Internet Group Multicast Protocol) is a session-layer protocol used to establish membership in a multicast group. The ADSL ATU-R supports both IGMP version 1 (IGMP v1) and IGMP v2. Select “Disabled” to disable it.

•IGMP Snoop: Enable the IGMP Snoop function if you need.

¾DHCP Server: Select Enabled, then you will see the screen below (shown in Figure 4-10). The Router will work as a DHCP Server, it becomes the default gateway for DHCP client connected to it. DHCP stands for Dynamic Host Control Protocol. The DHCP Server gives out IP addresses when a device is booting up and request an IP address to be logged on to the network. That device must be set as a DHCP client to obtain the IP address automatically. By default, the DHCP Server is enabled. The DHCP address pool contains the range of the IP address that will automatically be assigned to the clients on the network.

•Starting IP Address: Enter the starting IP address for the DHCP server's IP assignment. Because the default IP address for the Router is 192.168.1.1, the default Start IP Address is 192.168.1.2, and the Start IP Address must be 192.168.1.2 or greater, but smaller than 192.168.1.254.

•IP Pool Count: The max user pool size.

•Lease Time: The length of time for the IP lease. After the dynamic IP address has
