DESCRIPTION
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.
Internet Protocol. The underlying protocol for routing packets on the Internet and
other TCP/IP-based networks.
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 (Network Basic Input/Output System) are TCP or UDP packets that
enable a computer to find other computers.
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.
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.
Internet Group Multicast Protocol is used when sending packets to a specific
group of hosts.
Click Apply to save the filter settings. The settings then display in the summary
table at the bottom of the screen.
Clicking Apply saves your changes to the IES-1248-51's volatile memory. The
IES-1248-51 loses these changes if it is turned off or loses power, so use the
Config Save link on the navigation panel to save your changes to the non-
volatile memory when you are done configuring.
Click Cancel to begin configuring the fields afresh.
This table shows the ADSL port packet filter settings.
These are the numbers of the ADSL ports. Click this number to edit the port's
filter settings in the section at the top.
These are the packet filter settings for each port.
"V" displays for the packet types that the IES-1248-51 is to accept on the port. "-
" displays for packet types that the IES-1248-51 is to reject on the port (packet
types that are not listed are accepted). When you select PPPoE Only,"#"
appears for all of the packet types. With PPPoE Only, the IES-1248-51 rejects
all packet types except for PPPoE (packet types that are not listed are also
rejected).
