Norton Core & non-Norton VPN

I don’t think I have enough expertise or possibly growing old for this question... If I’m using my VPN a site will work fine, but as soon as I disconnect from my VPN, it gets blocked by the Core! Can someone explain why? Generally it’s the opposite! Thnx!

Re: Norton Core & non-Norton VPN

Using a VPN bypasses any DNS settings in your device or on your router. The DNS settings for the VPN servers takes precedence. Those DNS settings do not filter anything, so nothing will get blocked. 

When you disconnect your own VPN, the Core's DNS settings now take over. They include filtering for known malware sites, and other content types you have chosen to block.

Re: Norton Core & non-Norton VPN

I don’t understand. Regardless of the DNS settings (I’m using cloudflare), the Core is doing ALL the routing to/from your network, otherwise the Core would be useless! Just like either with or without VPN, it [the Core] STILL blocks bad sites! Also, the PC NAV would catch the bad stuff, again regardless of the DNS settings!

Re: Norton Core & non-Norton VPN

The filtering is done between the Core and the internet. Not after the Core to your devices.

The Core is basically a router with extra security features included. That router is set up to use a DNS service that filters your connections to protect you from sites known to have malware, or any other type of web site filtering you choose. ie Adult content, violent content, drugs etc. That is how the blocking is done.

When you use a VPN, all your outgoing and incoming data is encrypted before it leaves your device. The only thing that the Core can see is the IP address of your VPN provider, which is a safe web address. So it does not need to resolve a web address, ie www. whatever. com to an IP address. It is during this translation that any filtering is done. So if no translation is done, there is no filtering being done. So with a VPN active, you are able to freely access those sites that would normally be blocked by the Core router.

Any malware that might be on web sites that you connect to through the VPN connection would be caught by your Anti Virus software on your device as it was returned to your device.

Re: Norton Core & non-Norton VPN

If that is true, then why doesn't the PC NAV don't block it? If I turn off VPN, then it gets blocked.

I'm not referring to your typical porn or otherwise bad sites, I'm dealing w/a normal site, some stupid user page that I'm sure is connected with some company for promo. I understand the url catch, but, this is more of what the site is doing, and I don't know what! It's still puzzling. If it's trying to steal my info, why isn't the PC NAV don't catch it?

From what you're saying then, the Core is useless if I'm running a third party VPN! It'll be cheaper to just run NAV on all devices, which I'm already doing so on most, and I'll gain some speed. The only things that will not be protected are the IoT devices, but they will be somewhat protected if I'm running a good firewall on the router.

Re: Norton Core & non-Norton VPN

It depends on what kind of block you are seeing for that page. The Core can be much more aggressive in what it detects, depending on your filtering settings. The Safe Web features in Norton Security on your computer will only block known malicious or phishing sites.

As I noted above, when using a VPN all data in and out of the computer is encrypted. It is not readable data until it has already passed the router to your computer, where the data is then unencrypted for use on that computer. So there is nothing that the Core can scan to look for sites it would normally block. 

The bottom line is that using a VPN bypasses all protections in a router. Whether it is the Core, or any other router.

Re: Norton Core & non-Norton VPN

But if the data is finally readable on my computer end, then the NAV SHOULD catch what’s unsafe, wether it be a suspicious URL or a virus! Also, if someone tries to attack my network from an unprotected device, the router ought to see that. Gosh, last time I worked with these stuff was back in 2002, after 20+ years. Since then just doing the simple stuff! BTW thanks for putting up with my ignorance!

Re: Norton Core & non-Norton VPN

From my last post.

It depends on what kind of block you are seeing for that page. The Core can be much more aggressive in what it detects, depending on your filtering settings. The Safe Web features in Norton Security on your computer will only block known malicious or phishing sites.

What is the Core showing when the site you mention is being blocked?

Any malware that might come through would still be caught by the multiple layers of protection provided by Norton Security.

Re: Norton Core & non-Norton VPN

Looking at your image it shows that the category being blocked by the Core is Spam. The Norton Security does not block web pages based on possible spam. That is why you are not blocked when using Norton Security and your VPN. 

Everything sounds to be working as it should.
