NETGEAR UTM25-100NAS, UTM10EW-100NAS Extensive Protocol Support, Easy Installation and Management

ProSecure Unified Threat Management UTM10 or UTM25 Reference Manual

Extensive Protocol Support

The UTM supports the Transmission Control Protocol/Internet Protocol (TCP/IP) and Routing Information Protocol (RIP). For further information about TCP/IP, see “Internet Configuration Requirements” on page B-3. The UTM provides the following protocol support:

•IP address sharing by NAT. The UTM allows many networked PCs to share an Internet account using only a single IP address, which might be statically or dynamically assigned by your Internet service provider (ISP). This technique, known as NAT, allows the use of an inexpensive single-user ISP account.

•Automatic configuration of attached PCs by DHCP. The UTM dynamically assigns network configuration information, including IP, gateway, 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.

•DNS proxy. When DHCP is enabled and no DNS addresses are specified, the firewall provides its own address as a DNS server to the attached PCs. The firewall obtains actual DNS addresses from the ISP during connection setup and forwards DNS requests from the LAN.

•PPP over Ethernet (PPPoE). PPPoE is a protocol for connecting remote hosts to the Internet over a DSL connection by simulating a dial-up connection.

•Quality of Service (QoS). The UTM supports QoS, including traffic prioritization and traffic classification with Type Of Service (ToS) and Differentiated Services Code Point (DSCP) marking.

Easy Installation and Management

You can install, configure, and operate the UTM 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 firewall from almost any type of personal computer, such as Windows, Macintosh, or Linux. A user-friendly Setup Wizard is provided and online help documentation is built into the browser-based Web Management Interface.

•Auto detection of ISP. The UTM automatically senses the type of Internet connection, asking you only for the information required for your type of ISP account.

•IPsec VPN Wizard. The UTM includes the NETGEAR IPSec VPN Wizard to easily configure IPsec VPN tunnels according to the recommendations of the Virtual Private Network Consortium (VPNC) to ensure the IPsec VPN tunnels are interoperable with other VPNC-compliant VPN routers and clients.
