Getting Started
LAN-to-LAN applications. The RIP protocol exchanges routing infor-
mation between routers.
7. Domain Name Server (DNS) Proxy: The DNS proxy maintains a
DNS cache, including a mapping table between domain names and IP
addresses. The proxy also remembers DNS query packets sent
through the router and saves them into its own DNS cache. For
enhanced speed, when a DNS query packet enters the router, the
proxy searches its local DNS cache. If matched, the router sends an
answer to the host that sent the DNS query packet. Only unmatched
DNS queries require querying a WAN Domain Name Server.
8. Telnet Terminal Server: The Telnet User Interface (TUI) is an
efficient method of configuring and managing routers. It utilizes a
traditional command-line user interface and is mainly for advanced
configuration, management, and troubleshooting.
9. Dynamic Host Configuration Protocol (DHCP) Server: The server
provides an easy-to-configure function for your local IP network. It can
automatically assign IP network configurations for local PCs, such as
IP address, IP netmask, gateway IP address, and Domain Name server
etc.
10. Built-in Flash ROM: The Flash ROM memory saves the router
firmware and configurations, even after power down.
11. ISDN Digital Subscriber Line (IDSL) Client Support: If your
ISP provides ISDL connection, you can use the router to connect at
64/128k bps (U Interface Leased Line Type only).
12. Point-to-Point over Ethernet (PPPoE) Client Support: If you
are a DSL user, the router has a built-in PPPoE client for establishing
a DSL link connection with the ISP. There is no need to install a
further PPPoE driver on your computers.
13. Point-to-Ponit Tunnelling Protocol (PPTP) Client Support:
Some DSL modems (e.g. Alcatel modems) only provide a PPTP local
connection for an end user computer. The Vigor2000 Routers have a
1-8
