What are multi-hop and double VPN?
In the traditional wireless LAN, if you want to communicate with others, you must first access a fixed access point, called a single-hop network.
Accordingly, if each node in the network can send and receive signals and communicate directly with one or more peers, such a network is called a multi-hop network.
Benefits of multi-hop VPN
Using the multi-hop mode takes more than two nodes to send traffic over the Internet, and your data will pass through each node. So that is an effective solution to bypass all geographic restrictions and censorship while maintaining anonymity.
In a stable connection, the VPN server is the protective barrier between your device and the network. However, in multi-hop connections, the complexity of network connections increases exponentially, dramatically increasing the difficulty of tracking.
For example, your connection may be in the United States. Still, it may pass through Singapore, Mexico, and the United Arab Emirates before finally reaching your destination to hide your real location.
When a stable connection occurs, the traffic enters from the inlet node and is routed to the egress node to continue entering the Internet. That is great for increased privacy, but attackers can also gain information about the IP you're connecting from by monitoring network activity on the server.
When a multi-hop connection is matched after you connect to server A, it does not directly access the network. Still, it passes the request to server B through an encrypted tunnel, and server B transmits your access requirements to the network.
It becomes complicated for an attacker to track your traffic source due to multiple hops to increase privacy protection.
The more "hops" your data goes through before it reaches its destination, the more secure it is. That is because every time your data passes through a new network node, the chances of someone intercepting the communication between you and your final destination are greatly reduced. So this may be a good choice if you have higher requirements for network security protection.
