SIMPLY PUT, you make one easy change to your computer internet configuration and you’re using the free OpenDNS Domain Name System for faster and safer internet browsing. I suspect Vypyr's firewall service is something that filters traffic before it enters the VPN and travels to your endpoint, saving you the cost of having to carry that traffic only to drop it at your end.OpenDNS is a technology company that provides a simple solution to allow people to surf the web faster and more safely by using their Domain Name System. On the other hand, the firewall is still capable of having rules that result in blocking the VPN traffic itself (regardless of what the VPN traffic is), if configured to do so (which would mean that your VPN wouldn't work) - so you do need to be mindful of your firewall rules in that respect.Īlso, firewalls at the VPN endpoints can affect traffic, because they can see the traffic as it comes out of the VPN tunnel and becomes regular traffic. For instance, if a firewall is configured to block all incoming connections destined for the internal machine, that traffic will not be blocked by the firewall if it's encapsulated in the VPN, for the simple reason that the traffic, from the firewall's perspective, looks like the VPN traffic. I hope this explains the meaning of 'bypassing' in this context.įor maximum lulz, they're both wrong - and both right.Ī VPN will allow traffic that might otherwise have been blocked by an intermediate firewall to pass, simply because the traffic doesn't look like any that the firewall rules are designed to block. Which also means that if the VPN tunnel handles ALL your outgoing traffic, then any protection mechanisms that are applied at the SOHO router are now ineffective. Firewall and routing rules which would ordinarily apply to a packet are 'bypassed' by pushing the packet through the VPN connection. The net effect of this is that of a 'tunnel'.

The VPN client then wraps the entire IP datagram into another TCP packet (and at this precise moment the original packet becomes effectively invisible to the IP layer), and this packet is now sent to the VPN server (which unwraps it and then passes it on). The important part is that it then also alters your routing tables, which generally results in the fact that the IP layer now routes all or some of your outgoing traffic into the VPN client instead of directly out the interface. Now what happens when you establish a VPN connection? The VPN client creates a connection to a VPN server somewhere else. Your normal SOHO router/gateway/modem device will have a firewall that allows outgoing connections and any return packets for these.

It wraps the TCP packet into an IP datagram, puts the MAC address of the next hop router into it and hands it over to the ethernet interface, which transmits the whole shebang onto the wire.įirewalls work at the IP layer of this whole machinery (well, usually they do).

The IP layer decides, based on the IP address and its routing tables, where to send the packet (the next hop router, which is usually your default gateway). This packet is wrapped into a TCP packet, the name of the website is resolved to an IP address, and the TCP packet is handed over to the IP layer for routing. a particular web page, it creates an HTTP request.
