Dsl Router Configuration; Pppoe (Point-To-Point Protocol Over Ethernet); Dhcp (Dynamic Host Configuration Protocol) - Samsung SVR-1630 User Manual

Technical Note TN-0018

3.3. DSL Router Configuration

For this network configuration, DSL router does following tasks.
PPPoE to access Internet by getting official IP address from ISP.
DHCP function to provide local IP address to the clients on LAN
NAT to lead a client of a local IP address on Internet by providing official IP address.
NAPT (Port Forward / Virtual Server) to route incoming traffic to designated server on LAN.
Firewall to protect the client on LAN against attacks from outside.

3.3.1. PPPoE (Point-to-Point Protocol over Ethernet)

PPPoE is a network protocol for encapsulating PPP frames in Ethernet frames. It is used mainly with cable modem and
DSL services. It offers standard PPP features such as authentication, encryption, and compression.
SVR-1630 should be configured not to do PPPoE because DSL router does the process.

3.3.2. DHCP (Dynamic Host Configuration Protocol)

DHCP provides a means to allocate IP addresses dynamically to computers on a local area network (LAN). A network
administrator may configure DSL router with the range of IP addresses to DHCP and each client computer on the LAN
has its TCP/IP software configured to request an IP address automatically from the DHCP server in the router when that
client computer starts up.
SVR-1630 should be configured not to use DHCP feature, because SVR-1630 is a server and should be
accessed by incoming traffic through 'port forwarding'.
SVR-1630 should be configured to use a static local IP address which belongs to the LAN. Each
manufacturer's router uses LAN addresses as below and SVR-1630 can be assigned with the recommened IP
address.
DSL Router
D-Link, Linksys, Netgear
3Com, Netopia
Belkin, SMC
If the router limits IP addresses for the clients, SVR-1630 should be assigned an IP address of the
range.
