Don't like stealth blocked ports turned off

I had to turn it off so that my vpn would work. Now apparently my computer is vulnerable to being hacked.  And I quote " If Stealth Blocked Ports is turned off, Norton allows other computers to view the list of open and closed ports on your computer."  Norton needs to fix this.  How can I use my vpn without allowing other computers to view the list of open and closed ports on my computer?

Hello qimualaniq Have you attempted to setup a firewall program rule for your VPN? This article should help with that.

Re: Don't like stealth blocked ports turned off

HI, I was able to find "advanced" in the main window, but once I click on that, there is no Application Blocking row.  There is only a "smart firewall" row, under networking, which lets me turn it on or off.  So how do I setup a firewall program rule form my vpn?

Re: Don't like stealth blocked ports turned off

It appears that article is outdated somewhat. Under the "program control" tab look through the list of programs and check "allow" on the entry for your VPN. Make sure you save the settings and reboot the system. I am on NSBU version 22.16.2.22 and also do not see the settings the article suggests.

Re: Don't like stealth blocked ports turned off

If you are using a VPN, any scans of your connection are done on the VPN servers. They never reach your computer.

You can test that by enabling your VPN, checking your IP address at https://www.whatismyip.com/ , then doing a port scan using GRC (Gibson Research Corporation) ShieldsUP at  https://www.grc.com/x/ne.dll?bh0bkyd2  You will see that it is scanning the IP of the VPN server.

Re: Don't like stealth blocked ports turned off

Hi Peterweb: That's good to know, thank you.  Here's the thing: is that one port the only port available, or could there be others that  are now unprotected?   What about the times when I may for any reason be disconnected from the vpn?

Does Norton have that covered?

Re: Don't like stealth blocked ports turned off

Hi SoulAsylum: I believe you are now talking about going into settings, then firewall, then program control.

Yes, that was already set to "allow."   It was already blocking my vpn while it was set to "allow."

You can test by disabling your VPN and then running the ShieldsUp scan from GRC. Be sure you have restarted your browser between a test with the VPN active and inactive.

Re: Don't like stealth blocked ports turned off

Ok, I ran that test, and it did not show me any open ports.  What it did, apparently, is to check my router, and it passed:

THE EQUIPMENT AT THE TARGET IP ADDRESS DID NOT RESPOND TO OUR UPnP PROBES! (That's good news!)

So I guess this means I don't need to worry about this:

Stealth Blocked Ports

Norton Smart Firewall includes Stealth Blocked Ports to protect you from attackers who try to access your computer through open ports.

When you turn on Stealth Blocked Ports, Norton hides the status of your computer ports. Unused and blocked ports on your computer do not respond to network requests for data. By default, Stealth Blocked Ports is turned on.

If Stealth Blocked Ports is turned off, Norton allows other computers to view the list of open and closed ports on your computer.

Re: Don't like stealth blocked ports turned off

Yes sir you are good to go. My Verizon ISP device which is in front of my Core router responded the same. Core never even replied that it was aware of the probes, no alerts from NCSP. Although I DO NOT run a VPN port stealth on and off produced the same results.

This result shows you ran the UPnP test. That is good news for testing your router's exposure to UPnP attacks.

The port scans I suggested are initiated by clicking on the Common Ports or All Service Ports buttons. That will scan the ports on your computer. You may see a couple of ports as Closed, which is a good thing. If they are closed, they cannot be accessed by external scanners. Most will show Stealth. You can find information on any Closed ports by clicking on the port number on the left of the scan results.

The true stealth check results can also be exported to text for a later review. Thanks peter.
