[filter] =
[pppoe] Reject PPPoE packets. (Point-to-Point Protocol
over Ethernet) relies on PPP and Ethernet. PPPoE 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] Reject IP packets. Internet Protocol. The underlying
protocol for routing packets on the Internet and other TCP/
IP-based networks.
[arp] Reject ARP packets. 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] Reject NetBIOS packets. (Network Basic Input/
Output System) are TCP or UDP packets that enable a
computer to connect to and communicate with a LAN.
[dhcp] Reject DHCP packets. 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] Reject EAPol packets. 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] Reject IGMP packets. Internet Group Multicast
Protocol is used when sending packets to a specific group of
hosts.
[none] Accept all packets.
