Firewall switch from Home to Public on its own

Hi

My firewall settings changed from Home/Work to Public. I noticed that because Internet stopped working (Windows says Cant connect to Internet)

That happened on both of my computers at same time.

Interesting is that on another computer Internet was still OK, even with Ethernet setting on Public.

I solved issue with restarting Windows.

I have read that it is because Generic is set to OFF, and my IP is changed by my Internet provider as I don't have static IP.

Bitdefender sets Generic to OFF when it auto configures on install.

Should I change it on ON?

Am I right that this is the reason (IP change-is it possible that my provider changes IP address while computers are connected, I guess so)

After change to ON my settings will be

 

Ethernet Stealth Off, Generic On

Teredo Stealth Off, Generic On

Is that ok?

btw

That another computer later also changed to public (another day) and Internet stopped working.

When that happened there is only Etehrnet adapter present, no Teredo which comes back after reboot (and all on Home again)

and

I just looked at Ehternet settings, there was only Ethernet, on Home settings, but no Teredo. Then after a minute Teredo show up.

But settins are ok.

 

If this is indeed problem because of Generic set to Off instead on On, could Bitdefender team make default on On?

 

Best regards!
