Key Benefits

Features

Economical, Secure Shared Internet
Access

Router with four-port 10/100 Ethernet LAN
switch enables up to 253 simultaneous users
to securely share a single cable or DSL
Internet connection to leverage broadband
expenses.

Multiple Firewall Security Features

Stateful packet inspection firewall with
hacker pattern detection automatically
blocks malicious intrusions onto the local
network. Virtual DMZ and Network Address
Translation (NAT) features conceal the
private LAN from outside view while virtual
private network (VPN) support sets up
secure connections to remote sites or users
over the Internet. URL or keyword filtering
and allow/deny access control lists provide
spam and virus protection.

Robust Routing Features

IP routing (RIP 1 and 2) and static routing
allow the router to be used in multi-network
environments. Dynamic Domain Name
Service (DNS) enables users connecting to
the Internet with dynamic IP addresses to
use network applications such as Web or
FTP servers that normally require static IP
addresses.

Reliable and Simple to Use

Designed to meet 3Com's proven standards of
quality, reliability is assured and supported
by a three-year hardware warranty. Browser­based user interface, device discovery, and
simple setup wizards ease installation,
configuration, and administration.
