The IPSec (IP Security) protocol suite, based on modern cryptographic technologies, provides security services like 
encryption and authentication at the IP network layer. It secures the whole network traffic providing guaranteed 
security for any application using the network.  

You can use IPSec to create private secured tunnels between two hosts, two security gateways, or a host and a 
security gateway.  Up to three tunnels can be active at any given time. You can save more than three active 
tunnels, but they are not active.  

IPSec provides encryption and authentication services at the IP level of the protocol stack. IPSec can protect any 
traffic carried over IP. 

IPSec provides the following services: 

● 

Authentication only 

● 

Encryption only 

To transmit and receive data securely over an unprotected network:  

Select the type of IPSec service—authentication or encryption—required for the connection. 

Establish a secure connection by a key exchange process, using one of the following: 

● 

Manual Keying where the authentication and encryption keys are provided manually on both sides of the 
connection. 

● 

Auto Keying using IKEv2 Protocol where the authentication and encryption keys are generated on either 
side of the connection and exchanged by different methods. 

Transfer data using the connection.
