Q:

Concerns about a stealthed port

I run Ubuntu 14.04. Using the terminal, I did netstat -taupen to see what processes are running and I got this result:
Local Address        Foreign Address     State        User   Inode    PID/Program Name
192.168.1.3:54179    23.62.236.99:80     TIME_WAIT    0      0        -

Why is this ip connected to one of my ports? Also, ShieldsUp says port 54179 is stealthed, so what is going on? 

A:

Don't worry. Its the address of the remote peer you are connected to. Your source port is 54179 and the destination port is 80. This might be due to browsing some site or any other program using it,  the TIME_WAIT indicates that the connection has been closed from your end but waiting for any delayed packets from the remote peer. The IP (23.62.236.99) belongs to Akamai so it should be a part of CDN.
Here is a line while running netstat -taupen in my computer:
tcp        0      0 192.168.43.5:55720      104.16.19.44:80         ESTABLISHED 1000       44338       2045/firefox

This suggests that i have an active connection to 104.16.19.44 (Askubuntu) and the source port is 55720 and the destination port is 80 via the program firefox.
