Host-To-Host

This scenario shows how to configure IPSec between two single hosts which do not have a subnet behind them. Since there’s only host-to-host communication, both transport and tunnel mode can be used.

Test Host-To-Host Transport Mode

Description

Simple VPN configuration to connect two hosts using transport mode.

Scenario

Step 1: Set the following configuration in DUT0 :

set interfaces ethernet eth0 address 80.0.0.1/24
set system login user admin authentication encrypted-password '$6$GSjsCj8gHLv$/VcqU6FLi6CT2Oxn0MJQ2C2tqnRDrYKNF8HIYWJp68nvXvPdFccDsT04.WtigUONbKYrgKg8d6rEs8PjljMkH0'

set vpn ipsec site-to-site peer PEER tunnel 1 local prefix 80.0.0.2/32
set vpn ipsec site-to-site peer PEER tunnel 1 remote prefix 80.0.0.1/32

Step 3: Ping IP address 80.0.0.1 from DUT1:
