DSL-504T DSL Router User’s Guide B IP Address Setup The DSL-504T is designed to provide network administrators maximum flexibility for IP addressing on the Ethernet LAN. The easiest IP setup choice in most cases is to let the Router do it using DHCP, which is enabled by default. This appendix briefly describes various options including DHCP, used for IP setup on a LAN. If you are new to IP networking, the next appendix provides some background information on basic IP concepts.
DSL-504T DSL Router User’s Guide network), while the last three numbers denote the host IP address (each computer must have a unique address to distinguish it on the network). The IP address scheme used in Example #1 can be used for any LAN that requires up to 253 separate IP addresses (excluding the Router). Notice that the subnet mask is the same for all machines and the default gateway address is the LAN IP address of the Router.
DSL-504T DSL Router User’s Guide C IP Concepts This appendix describes some basic IP concepts, the TCP/IP addressing scheme and shows how to assign IP Addresses. When setting up the Router, you must make sure it has a valid IP address. Even if you will not use the WAN port (ADSL port), you should, at the very least, make sure the Ethernet LAN port is assigned a valid IP address. This is required for telnet, in-band SNMP management, and related functions such as “trap”handling and TFTP firmware download.
DSL-504T DSL Router User’s Guide Networks attached to the Internet are assigned class types that determine the maximum number of possible hosts per network. The previous figure illustrates how the net and host portions of the IP address differ among the three classes. Class A is assigned to networks that have more than 65,535 hosts; Class B is for networks that have 256 to 65534 hosts; Class C is for networks with less than 256 hosts.
DSL-504T DSL Router User’s Guide It is recommended that you choose private network IP Addresses from the above list. For more information on address assignment, refer to RFC 1597, Address Allocation for Private Internets and RFC 1466, Guidelines for Management of IP Address Space. Subnet Mask In the absence of subnetworks, standard TCP/IP addressing may be used by specifying subnet masks as shown below. IP Class Subnet Mask Class A 255.0.0.0 Class B 255.255.0.0 Class C 255.255.255.
DSL-504T DSL Router User’s Guide D Microfilters and Splitters Most ADSL clients will be required to install a simple device that prevents the ADSL line from interfering with regular telephone services. These devices are commonly referred to as microfilters or sometimes called (inaccurately) line splitters. They are easy to install and use standard telephone connectors and cable.
DSL-504T DSL Router User’s Guide Line Splitter If you are instructed to use a “line splitter”, you must install the device between the Router and the phone jack. Use standard telephone cable with standard RJ-11 connectors. The splitter has three RJ-11 ports used to connect to the wall jack, the Router and if desired, a telephone or telephone device. The connection ports are typically labeled as follows: Line - This port connects to the wall jack. ADSL – This port connects to the Router.
