= You can specify a single ADSL port <1>, all ADSL ports <*>
or a list of ADSL ports <1,3,5>. You can also include a range
of ports

= [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 broadcast 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.
