It is not surprising that today's needs demand more secure access to more resources from more remote unmanaged devices and platforms than ever before. Your island decides to build a bridge to another island so that there is an easier, more secure and direct way for people to travel between the two. Tunneling requires three different protocols. However, if the offices are very far apart, the cost can be prohibitively high - just like trying to build a bridge that spans a great distance.

Remote Access over an Intranet In some organization intranets, the data of a department, such as a human resources department, is so sensitive that the department's network segment is physically disconnected from the rest of the organization's intranet. Tunnel mode encrypts the header and the payload of each packet while transport mode only encrypts the payload. Communicate with the internet All resources in a virtual network can communicate outbound to the internet, by default. This can impact the performance of the device in that its flow cache may not be big enough to be effective. It is recommended that you review the design and deployment guides for each of the technologies that are used in this deployment. The same tunneling and encryption protocols are used.
