DSL-500 ADSL Router User's Guide for many user applications. A secure point-to-point connection is established between the user and the central office of the local telephone service provider. The user is always connected thus eliminating dial-up time and simplifying connectivity issues. Product Features The DSL-500 ADSL Router utilizes the latest ADSL enhancements and router technologies to provide a robust Internet gateway suitable for most small to medium sized offices. PPP (Point-to-Point Protocol) Security The DSL-500 ADSL Router supports PAP (Password Authentication Protocol) and CHAP (Challenge Handshake Authentication Protocol). DHCP Support (Dynamic Host Configuration Protocol) DHCP (Dynamic Host Configuration Protocol) allows IP addresses to be automatically and dynamically assigned to hosts on your network. Network Address Translation (NAT) For small office environments, the DSL-500 allows multiple users on the LAN to access the Internet concurrently through a single Internet account. This provides Internet access to everyone in the office for the price of a single user. NAT address mapping can also be used to link two IP domains via a LAN-to-LAN connection. TCP/IP (Transfer Control Protocol/Internet Protocol) The DSL-500 supports TCP/IP protocol, the language used for the Internet. It is compatible with access servers manufactured by major vendors. RIP-1/RIP-2 The DSL-500 supports both RIP-1 and RIP-2 exchanges with other routers. Using both versions will allow the Router to communicate with RIP enabled devices. Static Routing This allows you to select a data path to a particular network destination that will remain in the routing table and never "age out". This enables you to define a specific route that will always be used for data traffic from your LAN to a specific destination within your LAN (for example to another router or a server) or outside your network (to a ISP defined default gateway for instance). 2
