Chapter 22 Filtering
PPPoE Pass through Point-to-Point Protocol over Ethernet relies on PPP and Ethernet. It is a
specification for connecting the users on an Ethernet to the Internet through a
common broadband medium, such as a single DSL line, wireless device or cable
modem.
IP Pass through
Internet Protocol. The underlying protocol for routing packets on the Internet and
other TCP/IP-based networks.
ARP Pass through
Address Resolution Protocol is a protocol for mapping an Internet Protocol
address (IP address) to a physical computer address that is recognized in the
local network.
NetBios Pass
through
NetBIOS (Network Basic Input/Output System) are TCP or UDP packets that
enable a computer to find other computers.
DHCP Pass through Dynamic Host Configuration Protocol automatically assigns IP addresses to
clients when they log on. DHCP centralizes IP address management on central
computers that run the DHCP server program. DHCP leases addresses, for a
period of time, which means that past addresses are “recycled” and made
available for future reassignment to other systems.
EAPOL Pass
through
EAP (Extensible Authentication Protocol, RFC 2486) over LAN. EAP is used
with IEEE 802.1x to allow additional authentication methods (besides RADIUS)
to be deployed with no changes to the access point or the wireless clients.
IGMP Pass through Internet Group Multicast Protocol is used when sending packets to a specific
group of hosts.
