15ADSL ROUTER

WAN Settings :VPI and VCI

Virtual Path Identifier refers to an 8-bit (user to network packets) field within the header of an Asynchronous Transfer Mode cell

A Virtual Circuit Identifier (VCI) is a unique identifier which indicates a particular virtual circuit on a network. It is a 16-bit field in the header of an ATM cell

21ADSL ROUTER

DHCP Server

Dynamic Host Control Protocol (DHCP) server gives out IP addresses when a device is booting up and request an IP address to be logged on to the network

Starting IP address Ending IP address Client Table

22ADSL ROUTER

DNS Settings

The DNS Configuration allows the user to set the configuration of DNS relay

DNS relay selection Disable DNS relay or Use auto discovered DNS server only or Use user discovered DNS server only

Preferred DNS server - Enter the primary DNS server IP address

Alternate DNS server - Enter the secondary DNS server IP address

CETTM MTNL

23ADSL ROUTER

Virtual Server

The DSL Router can be configured as a virtual server so that remote users accessing Web or FTP services via the public IP address can be automatically redirected to local servers in the LAN network Depending on the requested service (TCP/UDP port number), the DSL router redirects the external service request to the appropriate server within the LAN network

Rule Name Private IP Protocol

24ADSL ROUTER

Filters

Filters are used to deny LAN computers from accessing the Internet. The Router can be setup to deny internal computers by their IP or MAC addresses. The DSL-502T can also block users from accessing restricted web sites
