In computing, '''Internet Protocol Security''' ('''IPsec''') is a secure network protocol suite of IPv4 that authenticates and encrypts the packets of data sent over an IPv4 network. IPsec includes protocols for establishing mutual authentication between agents at the beginning of the session and negotiation of cryptographic keys to use during the session. IPsec can protect data flows between a pair of hosts (host-to-host), between a pair of security gateways (network-to-network), or between a security gateway and a host (network-to-host). Internet Protocol security (IPsec) uses cryptographic security services to protect communications over Internet Protocol (IP) networks. IPsec supports network-level peer authentication, data-origin authentication, data integrity, data confidentiality (encryption), and replay protection.

If you have familiarized yourself with the configuration schemes and have all of the devices in order, we can start configuring the routers using instructions provided in this section.

**'''Enable''' - enables the IPsec instance

**'''Enable''' - enables the IPsec instance

***'''Host''' - hostname or IP address to which ICMP packets will be sent to. Best to use a hostname/IP address belonging to the opposite instance's LAN. For this example we just use the other router's LAN IP address

***'''Host''' - hostname or IP address to which ICMP packets will be sent to. Best to use a hostname/IP address belonging to the opposite instance's LAN. For this example we just use the other router's LAN IP address

***'''Ping period (sec)''' - the period (in seconds) at which ICMP packets will be sent to the specified host

***'''Ping period (sec)''' - the period (in seconds) at which ICMP packets will be sent to the specified host

**'''Allow WebUI access''' - when checked, allows WebUI access for hosts from the opposite instance

**'''XAUTH''' - this option is only available when IKEv1 is selected. When enabled, it can be used for additional authentication.

'''NOTE''': remember to replace certain parameter values (like IP addresses) with your own relevant data.

After Clicking on “Save & Apply” for both the routers we can try pinging the remote LAN IP to see if its reachable. Also using the command “ipsec status” in CLI will show the status of the IPsec Connection.

==Testing the setup==

==Testing the setup ==

If you've followed all the steps presented above, your configuration should be finished. But as with any other configuration, it is always wise to test the setup in order to make sure that it works properly. To test an IPsec connection, you could use the command “ipsec status” in CLI. It will show the status of the IPsec Connection similar to the ones shown below. You can also '''ping''' the opposite instance's VPN IP address. To use a ping command, type '''ping <ip_address>''' and press the "Enter" key on your keyboard:
