8.1.5
Current DHCP Reservation
This area of the screen continually updates to show all DHCP enabled
computers and devices connected to the LAN side of your router. The
detection "range" is limited to the address range as configured in DHCP
Server. Computers that have an address outside of this range will not
show. If the DHCP Client (i.e. a computer configured to Automatically
obtain an address) supplies a Host Name then that will also be shown.
Any computer or device that has a static IP address that lies within the
detection "range" may show, however its host name will not.
8.1.6
IGMP Multicast memberships
If IGMP is enabled, this area of the screen shows all multicast groups of
which any LAN devices are members.

The IP address and, where appropriate, port number of the local
application.
NAT.
The port number of the LAN-side application as viewed by the WAN side
application.
Internet.
The IP address and, where appropriate, port number of the application on the Internet.
Protocol.
The communications protocol used for the conversation.
State.
State for sessions that use the TCP protocol.
NO: None -- This entry is used as a placeholder for a future connection that may occur.
SS: SYN Sent -- One of the systems is attempting to start a connection.
EST: Established -- The connection is passing data.
FW: FIN Wait -- The client system has requested that the connection be stopped.
CW: Close Wait -- The server system has requested that the connection be stopped.
TW: Time Wait -- Waiting for a short time while a connection that was in FIN Wait is fully closed.
LA: Last ACK -- Waiting for a short time while a connection that was in Close Wait is fully closed.
CL: Closed -- The connection is no longer active but the session is being tracked in case there are any retransmitted packets still pending.
Dir.
The direction of initiation of the conversation:
Out. Initiated from LAN to WAN.
In. Initiated from WAN to LAN.
Priority.
The preference given to outbound packets of this conversation by the QoS Engine logic. Smaller numbers represent higher priority.
Time Out.
The number of seconds of idle time until the router considers the session terminated. The initial value of Time Out depends on the type
and state of the connection.
300 seconds. UDP connections.
240 seconds. Reset or closed TCP connections. The connection does not close instantly so that lingering packets can pass or the
connection can be re-established.

The Logs sub-menu allows you to view the router logs. The router
automatically logs (records) events of possible interest in its internal
memory. If there isn‟t enough internal m
emory for all events, logs of
older events are deleted but logs of the latest events are retained. You
can decide what types of events you want to view and the level of the
events to view. This router also has external Syslog Server support so
you can send the log files to a computer on your network that is
running a Syslog utility.

The routing section displays all of the routing details configured for your
router.
A value of 0.0.0.0 for gateway means there is no next hop, and the IP
address is directly connected to the router on the interface specified: LAN or
WAN. A value of 0.0.0.0 in both the destination IP and netmask means that
this is the default route.
