You must declare that the routes are bidirectional in order for this to happen. To put it another way, while the distant network can see the private network, the private network cannot always see the remote network. The main concept is to use the tunnel to transport traffic for all private networks (10.0.0, 172.16.0.0, and 192.168.0.0). Local routing information on the routers was excluded for the sake of a simplified diagram (Figure 1). The local IP address 192.168.12.0 is used by the remote network. The Client Router is a Linux system that serves as the remote network's firewall or gateway. Here are some diagrams to help visualize this notion (using IP masquerading): Simply put, a VPN is created by creating a secure tunnel between two networks and routing IP via it.
Section (c) - So, how does a virtual private network (VPN) work?
You can also join two small (or large) networks together to create a single larger network. Remote workplaces or employees working from home are prominent examples of remote nodes. The most frequent design is to have a single primary internal network with remote nodes accessing the central network through VPN. It all relies on how your network is set up. This question can be answered in a variety of ways. Section (b) - But what exactly IS a virtual private network (VPN)? The term VPN refers to a virtual private network that uses the Internet as its transport mechanism while keeping the data on the VPN "secure". Theoretical understanding Section (a) - What is a virtual private network (VPN)? While protecting your privacy is crucial, this does not need signing up for a VPN service and tunneling all of your internet activity via VPN servers.Įnough jibber-jabber from me let's get on with the guide. People are (legitimately) concerned about their privacy after the senate voted to allow internet service providers (ISPs) to sell your personal information to advertisers. The internet is a challenging place for those who value their privacy.
