Firewall traffic rules
I was looking at the firewall traffic rules that are in place for my computer and am not sure if they are configured correctly.
Default BLOCK inbound NetBios name
BLOCK, Direction: inbound; Computer: any; Communications: specific; Protocol: UDP
At first glance, it looks good. However, when I clicked on Modify, and then Communications, I noticed that the rule specifically blocks "ONLY communications that match all the types and ports listed below" which was listed as follows: "local netbios-ns (port 137)".
There is another line regarding NetBios that is listed. That is the same as above except it blocks only "local netbios-dgm (port 138).
Does that mean that every other port is NOT BLOCKED to inbound traffic for these situations?
I ran a test on Spybot Search and Destroy to see what I had for open network ports and both of those ports (137 and 138) are listed as open under the local port heading with a flag of UDP Listen. At the time, there were 17 ports listed as LISTENING, one as ESTABLISHED and one as TCP CLOSE_WAIT.
I then went to Shield's Up website and failed the test because they were able to get to my personal network IP.
I don't know enough about Network security and firewalls to know if something is really wrong or not and don't want to arbitrarily change things around without getting some advice. (I did have someone from Norton set-me up originally, but that was months ago). I have read in various forums mixed results of using the Smart Firewall or Automatic option. Some people suggest turning that off and configuring the firewall on ones own to avoid problems.
Can someone help me? I have only given one example of the Firewall Traffic Rules, but I have many I'd like to go over with someone.
