| The roadwarriors <b>carol</b> and <b>dave</b> set up a connection each to gateway <b>moon</b>. |
| The key exchange is based on NTRU encryption with a cryptographical strength of 128 bit and |
| 192 bit for <b>carol</b> and <b>dave</b>, respectively. Authentication is based on strong |
| preshared keys (PSKs). |
| Both <b>carol</b> and <b>dave</b> request a <b>virtual IP</b> via the IKEv2 configuration payload |
| by using the <b>leftsourceip=%config</b> parameter. The gateway <b>moon</b> assigns virtual |
| IP addresses from a simple pool defined by <b>rightsourceip=10.3.0.0/28</b> in a monotonously |
| increasing order. |
| <p> |
| <b>leftfirewall=yes</b> automatically inserts iptables-based firewall rules that let pass |
| the tunneled traffic. In order to test the tunnels, <b>carol</b> and <b>dave</b> then ping |
| the client <b>alice</b> behind the gateway <b>moon</b>. The source IP addresses of the two |
| pings will be the virtual IPs <b>carol1</b> and <b>dave1</b>, respectively. |
