What if you Email Server is accessible only from your office. If yu are not on your office Intranet, you will not be able to access your work email. Same applies for all the intranet sites, that are accessible when you are in office only.

This is the common type of setup in most of the companies.

So, while you are travelling you can not check your official email, unless you are connected to your office Intranet, and yu can do it using VPN client software.

But why should your company allow anyone from outside to access their internal servers, security risk ?? No, because, once connected via VPN , there's an encrypted, secure channel between your pc and your company's n/w, which no one can see, over the public internet.

Once you are connected, you are a part of your Intranet onec again.

SAme applies for a site to site tunnel, two branches of a company using private addresses, wants to cmmunicate over the Public Internet, securely, then the only solution they have is VPN.

Let me know if yo have more questions.
