What Are the Features of This Product?
Feature Description
Uses Network Address Translation (NAT)
and Port Address Translation (PAT)
intelligently together to send packets
over the network, and translates public
addresses to private ones.
An address translation protocol that
supports simultaneous connections from
different workstations on the LAN with
one public IP address.
An address translation protocol that
supports simultaneous connections from
different workstations on the LAN with
one or more public IP addresses. The
mapping can be done dynamically or
statically.
There are two types of NAT:
Dynamic NAT — Dynamically maps a


public address from a pool of
addresses to the private address of
your workstation on your LAN.
Static NAT— Statically maps a public


address to the private address of your
workstation on your LAN.
A protected computer network that acts
like a private network over the Internet.
When the MPPE and PPTP protocols are
used together, a VPN is created.
Negotiates and establishes a connection
between two peers to provide a
standard method for transporting
multi-protocol datagrams over
point-to-point links. Sets the MSCHAPv1
authentication protocol.
Tunneling protocols that you use to
protect and configure a VPN.
An encryption protocol used to make a
tunnel private.
Supported by Microsoft CHAPv1, an


authentication protocol set with the
PPP command.
Allows SIP telephones to connect to
Ethernet ports.
