FIREWALL - NETWORK & CONNECTION NOTIFICATION

Recently I seen a report from Recent History under Firewall - Network & Connection as per screen attached that I connected to Public Network with IP address 127.0.0.0./255.0.0.0, please advice whether this IP address is the my Modem LAN (I connected to Home Internet), what is the meaning "Public Network" as I have set the Network Trust as Restricted in Firewall menu.

Another what is the meaning "Protecting your connection to newly detected network on adapter Software Loopback Interface IP 127.0.0.1.

Please explain and advice.

Thanks & B/regards,

Re: FIREWALL - NETWORK & CONNECTION NOTIFICATION

Hello. The IP address 127.0.0.1 IS your internal firewall loopback, also referred to as “localhost”. In other words your internet connection and the base from which IP addresses are assigned. Setting your firewall to "restricted" will also block most traffic and give you notifications as well. My Norton firewall trust is set to "private".

If you have your network set to "public" vice "private" Windows and Norton firewalls will restrict usage of certain devices and resources. Have a look at this article to set your network to private on your home network. https://answers.microsoft.com/en-us/windows/forum/windows_10-networking/public-versus-private-network-mystery/7964cfbf-cf49-45a7-9fab-86d9e6b9c28a

Re: FIREWALL - NETWORK & CONNECTION NOTIFICATION

127.0.0.1 is a loopback address that allows software to communicate internally on your computer.  The address is on the 127.0.0.0 network.  Essentially, the firewall is just informing you that it is monitoring this internal network and its connections.

As for "public" vs. "private," do not think of them as networks - rather, think of them as firewall configurations that are tailored to two specific situations:  When you are connected to a private network, such as your secured home router's wifi, the firewall will configure itself to permit your other networked devices to find and communicate with your computer so you can easily do things like sharing files.  "Private," therefore means that the protocols used for these purposes will be allowed.  On the other hand, when you are connected to a public network, such as public wifi, the firewall configures itself as "Public" to be more restrictive, blocking those protocols to prevent other devices on the network from accessing your PC.  Even if you select "Restricted" to prevent connections to any other devices on a network, the internal loopback network needs to be accessible by software on your system, so Norton automatically allows for that.

Re: FIREWALL - NETWORK & CONNECTION NOTIFICATION

Dear all,

Thank you for your kind information and explanation, so to avoid the "Stranger Guys" to connect my home network its better to select the Network to "Restricted" or Public to avoid any interfere communication, therefor I suggest for the next Norton Security product to be add the Home Network Mapping so the user can monitor who are connecting to the Home Network.

My question when I select to Public Network can I use My Share Printer?

Best regards,

Re: FIREWALL - NETWORK & CONNECTION NOTIFICATION

Yes, you shouldn't have a problem sharing your printer with your network set to Public.

A little bit of knowledge is... well a little bit of knowledge.
