NAT
(Network Address Translation)
An IETF standard that allows an organization to present itself to the Internet with
far fewer IP addresses than there are nodes on its internal network. The NAT
technology, which is typically implemented in a router, converts the private IP
addresses (such as in the 10.0.0.0 range) of the node on the internal private
network to one IP address or one of several IP addresses for the public Internet.
NAT not only conserves public IP addresses, but it also serves as a firewall by
keeping internal addresses hidden from the outside world. Implementations also
often include port address translation (PAT), which can alter the port numbers in
the header, adding another level of differentiation.
PPPoE
(Point-to-Point Protocol Over Ethernet)
A standard for incorporating the popular PPP protocol, widely used for dial-up
Internet connections, into a cable modem connection that uses Ethernet as its
transport to the carrier's facilities. Used by a large number of cable modem
providers, PPPoE supports the protocol layers and authentication widely used in
PPP and enables a point-to-point connection to be established in the normally
multipoint architecture of Ethernet.
PPTP
(Point-to-Point Tunneling Protocol)
A protocol from Microsoft that is used to create a virtual private network (VPN) over
the Internet. It uses encryption based on RSA's RC4, known as Microsoft Point-to-
Point Encryption (MPPE). Remote users can access their corporate networks via
any ISP that supports PPTP on its servers.
SUA
Single User Account (SUA)
Allows multiple workstations on your LAN to access the Internet for the price of an
individual account. SUA accomplishes this through a mechanism called Network
Address Translation (NAT) that makes your whole LAN appear as a single host to
the Internet. You may hear other names such as "IP masquerading" or "IP
sharing", but basically they mean the same thing.
If your ISP assigns you no address at all or only one IP address, then you have a
single user account, and so you must enable SUA.
You can designate one inside server machine on your LAN to be accessible to the
outside world under SUA. Please note that this one machine can host multiple
services, e.g., you can run a web server, an FTP server and a telnet server all on one
machine. SUA offers the added benefit of firewalling if you do not define a server.
TFTP
(Trivial File Transfer Protocol)
A version of the TCP/IP FTP protocol that has no directory or password capability.
UPnP
(Universal Plug aNd Play)
A set of standards for interoperability of networking devices from Microsoft and the
UPnP Forum. UPnP extends the Plug and Play concept to network devices so that
they can be installed and set up without manual intervention. For example, the
UPnP Internet Gateway specification enables residential Internet gateways to be
automatically configured to handle multiple PCs in a home network.
