Chapter 2 Introduction This chapter describes the features of the NETGEAR DG834 ADSL Modem Router. The DG834 ADSL Modem Router is a combination of a built-in ADSL modem, modem router, 4-port switch, and firewall which enables your entire network to safely share an Internet connection that otherwise would be used by a single computer.
Content filtering These features are discussed below. A Powerful, True Firewall Unlike simple Internet sharing NAT routers, the DG834 v3 is a true firewall, using stateful packet inspection to defend against hacker attacks. Its firewall features include: • Denial of Service (DoS) protection Automatically detects and thwarts Denial of Service (DoS) attacks such as Ping of Death, SYN Flood, LAND Attack and IP Spoofing.
Reference Manual for the ADSL Modem Router DG834 Easy Installation and Management You can install, configure, and operate the DG834 v3 within minutes after connecting it to the network. The following features simplify installation and management tasks: • Browser-based management Browser-based configuration allows you to easily configure your modem router from almost any type of personal computer, such as Windows, Macintosh, or Linux.
Page 18
• Automatic Configuration of Attached PCs by DHCP The DG834 v3 dynamically assigns network configuration information, including IP, modem router, and domain name server (DNS) addresses, to attached PCs on the LAN using the Dynamic Host Configuration Protocol (DHCP). This feature greatly simplifies configuration of PCs on your local network.
Auto Sensing and Auto Uplink™ LAN Ethernet Connections With its internal 4-port 10/100 switch, the DG834 v3 can connect to either a 10 Mbps standard Ethernet network or a 100 Mbps Fast Ethernet network. The local LAN ports are autosensing and capable of full-duplex or half-duplex operation.
Warranty and Support Information Cards • Two plastic feet that can be used to stand the DG834 ADSL Modem Router on end. If any of the parts are incorrect, missing, or damaged, contact your NETGEAR dealer. Keep the carton, including the original packing materials, in case you need to return the product for repair.

Two common scenarios for configuring VPN tunnels are between a remote personal computer and a network gateway and between two or more network gateways. The DG834 v3 supports both of these types of VPN configurations. The DG834 ADSL Modem Router supports up to five concurrent tunnels.
A VPN client access allows a remote PC to connect to your network from any location on the Internet. In this case, the remote PC is one tunnel endpoint, running the VPN client software. The DG834 ADSL Modem Router on your network is the other tunnel endpoint. See “How to Set Up a Client-to-Gateway VPN Configuration”...
A VPN between two or more NETGEAR VPN-enabled routers is a good way to connect branch or home offices and business partners over the Internet. VPN tunnels also enable access to network resources across the Internet. In this case, use DG834 v3s on each end of the tunnel to form the VPN tunnel end points. See “How to Set Up a Gateway-to-Gateway VPN Configuration”...
Page 92
Reference Manual for the ADSL Modem Router DG834 This set of configuration information defines a security association (SA) between the two VPN endpoints. When planning your VPN, you must make a few choices first: • Will the local end be any device on the LAN, a portion of the local network (as defined by a subnet or by a range of IP addresses), or a single PC? •...
You have more control over the process, however the process is more complex and there are more opportunities for errors or configuration mismatches between your DG834 v3 and the corresponding VPN endpoint gateway or client workstation.
