6.5.5 Internet Session Status
ƒ Click on the Internet Sessions link in the navigation drop-down menu. The Internet
Sessions page displays full details of active Internet sessions through your router. An
Internet session is a conversation between a program or application on a LAN-side
computer and a program or application on a WAN-side computer.
ƒ Local: The IP address and, where appropriate, port number of the local application.
ƒ NAT: The port number of the LAN-side application as viewed by the WAN-side
application.
ƒ Internet: The IP address and, where appropriate, port number of the application on
the Internet.
ƒ Protocol: The communications protocol used for the conversation.
ƒ State: State for sessions that use the TCP protocol.
o NO: None -- This entry is used as a placeholder for a future connection that
may occur.
o SS: SYN Sent -- One of the systems is attempting to start a connection.
o EST: Established -- the connection is passing data.
o FW: FIN Wait -- The client system has requested that the connection be
stopped.
o CW: Close Wait -- the server system has requested that the connection be
stopped.
o TW: Time Wait -- Waiting for a short time while a connection that was in FIN
Wait is fully closed.
o LA: Last ACK -- Waiting for a short time while a connection that was in Close
Wait is fully closed.
o CL: Closed -- The connection is no longer active but the session is being
tracked in case there are any retransmitted packets still pending.
ƒ Priority: The priority given to packets sent wirelessly over this conversation by the
WISH logic. The priorities are:
o BK: Background (least urgent).
o BE: Best Effort.
o VI: Video.
o VO: Voice (most urgent).
ƒ 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.
o 300 seconds - UDP connections.
o 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.
o 7800 seconds - Established or closing TCP connections.
