Running Norton 360 on windows 10.
About 4 months ago I saw the same thing and posted a question asking why both networks showed internet access. Did not receive an answer that explained it. Then about 2 months ago when I accessed my private wifi network and turned on VPN it would show no internet access for the private wifi and internet access for my Norton SecureVPN which I thought should be correct.
Now I'm back to seeing Internet access on both my private wifi network and my NortonSecureVPN.
