the incoming traffic is allowed. If no match is found, the

incoming traffic is discarded.

• Virtual Private Network (VPN)

The Wireless Barricade Plus supports two of the most commonly

used VPN protocols – PPTP and IPSec. These protocols allow

remote users to establish a secure connection to their corporate

network. If your service provider supports VPNs, then any of these

protocols can be used to create an authenticated and encrypted

tunnel for passing secure data over the Internet (i.e., a

traditionally shared data network). The VPN protocols

supported by the Wireless Barricade Plus are briefly described below.

• Point-to-Point Tunneling Protocol (PPTP) – Provides a secure

tunnel for remote client access to a PPTP security gateway. PPTP

includes provisions for call origination and flow control required

by ISPs.

• IP Security (IPSec) – Provides IP network-layer encryption. IPSec

can support large encryption networks (such as the Internet) by

using digital certificates for device authentication.
