VPN Settings
VPN (Virtual Private Networking) provides for secure
communication between two separate networks
without using a dedicated leased line. In order to
achieve this functionality, a secure tunnel must be built
between the two sites for secure communication over
the Internet. The BOSS™ supports the two most
popular protocols, IPSec and PPTP.
IPSec provides encryption and authentication
services at the IP layer. Working at this level, IPSec
can protect any traffic carried over IP unlike other
encryption methods that only protect a particular
higher-level protocol.
PPTP (Point-to-Point Tunneling Protocol), is a PPP-
specific protocol proposed by Microsoft. The BOSS™
implements a PPTP server. The remote user can con-
nect to the PPTP server and access a local host
behind the PPTP server.
How to change your VPN settings
When you select the VPN item in left menu of the web
page, IPsec and PPTP configuration options will
appear. Please refer to the corresponding sections for
these configurations.
