PPPoE
The Point-to-Point Protocol over Ethernet (PPPoE) encapsulates IP data packets
over point-to-point links (such as a link from a home computer to the Internet via
an Internet Service Provider). This link is authenticated with a username and
password and then PPP communication can take place between two network
devices (your router and your Internet Service Provider firewall).
See RFC2516.
PPTP
The Point-to-Point Tunneling protocol uses a version of GRE (Generic Routing
Encapsulation) to transport PPP packets. A username, password and IP address
of the PPTP server is required to receive IP address parameters. This is
frequently used by Microsoft Windows as a way of creating Virtual Private
Networks. See the chapter on PPP in the reference manual for more information.
Proxy DNS
A device which pretends to be a DNS server but actually forwards all DNS
requests to a remote server is called a Proxy DNS. For instance, clients on a local
network will make DNS requests to a Proxy DNS device which in turn forwards
those requests to the appropriate external DNS server. Frequently there is a cache
that keeps a list of frequently requested names so that the responses from the local
network can be replied to quickly.
Reboot
Rebooting is when your router is powered off and then turned back on again.
This happens either when your remove the power connection to the device or
your local power supply is interrupted (a blackout for example.) After reboot the
device will check to be sure all of the hardware is working correctly and then load
in the “Boot Config”. Any changes that were made to the “Current Config” will
have been erased after the reboot.
RFC
Request For Comments are documents that define standards on the Internet. They
are a good resource when you need detailed information on a particular aspect of
your network. Fortunately there are many databases of these documents such as at
