The ADTRAN NetVanta

®

2050 and 2054

are Small Office/Home Office VPN/Firewall
gateways providing all the necessary
components required to secure an
integrated VPN solution.

Used primarily for

remote access, the NetVanta 2050 and 2054
are perfect for work-at-home telecommuters
needing to have a secure connection back to
corporate resources. Based on the ADTRAN
Operating System (AOS), the NetVanta 2050
and 2054 provide key security and data
protection features such as IPSec VPN
tunneling, stateful inspection firewall, IP
routing, Network Address Translation (NAT ),
and even a DHCP server. The 2050 and 2054
support the same features and perform the
same functions, but the 2054 adds a built-in
four-port 10/100Base-T Ethernet switch.

Security

On a public infrastructure like the Internet,
security is of the utmost importance. The
NetVanta 2050 and 2054 employs a stateful
inspection firewall that protects an organiza-
tion’s network from common Denial of
Service (DoS) attacks including TCP
synflooding, IP spoofing, ICMP redirect, ping-
of-death, and IP reassembly problems.

For the telecommuter that needs a

dedicated firewall without corporate VPN
access, the NetVanta 2050 and 2054 offer
a firewall only version. The firewall only
versions offer the same basic features,
without IPSec VPN tunneling, encryption
and authorization.

VPN Tunneling

The NetVanta 2050 and the 2054 are IPSec-
compliant devices that provide secure
communications over potentially unsecure
networks. As security gateways, both the
NetVanta 2050 and 2054 supports up to five
simultaneous VPN tunnels and up to 15 users
on the LAN, while supporting encryption
algorithms including DES, 3DES, and AES.
In addition, these devices support IKE
(Internet Key Exchange) and X.509 digital
certificates for user authentication.

Management

NetVanta’s web-based GUI or CLI can be used
for secure local or remote configuration of
any NetVanta 2050 and 2054. For a central-
ized, enterprise-wide management scheme,
ADTRAN offers n-Command

™

, an intuitive,

scalable software suite for managing larger
NetVanta deployments and features robust
productivity tools to effectively manage a
distributed network. To administer user
accounts, the NetVanta 2050 and 2054 utilizes
XAUTH using RADIUS and RSA SecurID to
manage administration account lists. These
devices also offer built-in alert and logging
mechanisms to warn administrators about
activities that are going on in the network.

Quality of Service (QoS)

QoS is also supported for delay sensitive
traffic like VoIP or video. To prioritize
mission critical traffic and control network
congestion, the NetVanta 2050/2054 uses
Low Latency Queuing, Weighted Fair
Queuing ( WFQ), Class-based WFQ, and
DiffServ marking to establish priority of
IP packets routed over the network.

VoIP Ready

In combination with the QoS features, a
specialized SIP Application Layer Gateway
(ALG) allows SIP traffic to traverse NAT-
enabled firewalls. For an enterprise network,
this interoperability allows IP PBXs, phones,
and other SIP-based devices to set up, tear
down, and pass voice and call control
messages seamlessly through the integral
NAT-enabled firewall.

Interoperability

The NetVanta 2050 and 2054 offers the
highest level of integration with ADTRAN’s
complete line of IPSec VPN equipped
NetVanta products: NetVanta Ethernet
Switches, NetVanta Access Routers, and
NetVanta VPN/Firewall appliances. Together
the NetVanta Series offers the most robust
set of feature to address a wide range of
enterprise VPN needs.
