Difference between a Site-to-Site VPN and a VPN client
When you use a Site-to-Site VPN it connects all networks to each other. For example, you can connect a branch office network and the headquarter networks to each other. When connected to a S2S VPN, hosted don’t have a VPN client software, but it sends and received TCP/IP traffic through a VPN gateway device. The VPN device is in charge to make sure that the outbound traffic is encapsulated and encrypted while sending it though a VPN tunnel on the internet. At the end it peers VPN gateway to the target site where it strips the headers and decrypts the content.
On the other hand, remote accessVPNs connect individual users to private networks. For example, it’s used by travelers or teleworkers that have to access their organisation’s network. It provides security over the internet. In this case, every user has to have their own VPN software. Whenever a user wants to send any traffic, the VPN software takes care of encapsulating and encrypting the traffic and data before it goes through the internet to the VPN gateway. When it receives the traffic, the following process continues the same as for the Site-to-Site VPNs.
The most popular and secure tunnelling protocol used for Site-to-Site VPNs is the IPsec ESP.
