Virtual Private Networking
3Com offers a comprehensive range of VPN solutions, making
it easy for you to utilize a shared IP network such as the
Internet. The SuperStack II NETBuilder SI platforms support
Virtual Leased Line (VLL) to establish a secure corporate
intranet to remote/branch offices, a secure extranet for busi-
ness partners and e-commerce, and secure remote access for
mobile workers.
■
The platforms support standards-based PPTP and L2TP,
IPSec, MPPE, plus Internet Key Exchange (IKE), increasing
remote access performance and security.
■
With 3Com’s versatile VLL solution you can maintain your
business critical applications over the existing WAN and
use VLL to send only lower priority traffic, use VLL as a low
cost backup for disaster recovery on an existing network,
or use VLL for temporary augmentation of overflow traffic.
■
Remote Authentication Dial-In User Service (RADIUS),
Extensible Authentication Protocol (EAP), and LDAP
Client are available on the platforms to provide
authentication support.
