UPnP port openings
« on: September 27, 2011, 02:07:28 PM »
I have not yet found any way to display which ports have be opened (and to what machine on my LAN) via the UPnP protocol.  I just want to make sure that I have no openings in my FW that I am unaware of.  Anyone out there been able to do this?

What are you trying to do excatly? What do you mean by FW? Firmware or Firewall?
If your concerned about firewalls, there really no need for 3rd party firewalls as the routers firewall does it's job for blocking and you can always add addition information on the router to block items too. Having an additional firewall in the home with a router is kind of redundent when most eveil do'ers are going after more high profile networks like corporate and Gov. IMO.

I think he is looking for

192.168.0.1 > Status > Internet Sessions > Look under "Internet"

That will give you the IP then the port like

64.78.164.232:80

Which is forums.dlink.com on port 80, or HTTP. If its TCP traffic, you can get extra info by looking at the port state:

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CL: Closed -- The connection is no longer active but the session is being tracked in case there are any retransmitted packets still pending.

Hope that helps
