Allows multiple users at a site to share the same digital subscriber line, cable modem, or
wireless connection to the Internet. You can configure PPPoE client instances, including the
username and password, on any or all interfaces on some security devices.
A security policy is the combination of both firewall rulebases and all rules into a comprehensive
plan that defines how the security device works on your network.
The translation of the original source port number in a packet to a different, randomly
designated port number.
The translation of the original destination port number in a packet to a different, predetermined
port number.
A feature supported on some security devices, port mode allows you to select one of several
different sets of port, interface, and zone bindings on the device. Changing the port mode
removes any existing configurations on the device and requires a system reset.
A port scan attack occurs when packets are sent out to different port numbers, for the purpose
of scanning the available services in hopes that one port will respond. If a remote host scans
10 ports in 0.3 seconds, the security device flags this as a port scan attack and drops the
connection.
A value associated with a route that the virtual router uses to select the active route when
there are multiple routes to the same destination network. The preference value is determined
by the protocol or origin of the route. The lower the preference value of a route, the more likely
the route is to be selected as the active route.
An IP address that represents a route.
The process status displays information about processes on a security device.
Protocols are predefined services (HTTP, SNMP, Telnet, and so on) that are enabled for the
security device.
Protocol Type.
Remote Authentication Dial-In User Service is a service for authenticating and authorizing
remote access service (RAS) users.
RAS is the acronym for remote access services, which enable users to access services protected
by your security devices. Typically, you use a VPN to enable RAS, then add RAS users to the
VPN.
RTSP is an application layer protocol for controlling the delivery of a stream of real-time
multimedia content.
