| A connection between the subnets behind the gateways <b>moon</b> and <b>sun</b> is set up. |
| The authentication is based on <b>X.509 certificates</b> containing <b>Ed25519</b> keys. |
| <b>moon</b> uses the wolfssl plugin based on the wolfCrypt library for all |
| cryptographical functions whereas <b>sun</b> uses the default strongSwan |
| cryptographical plugins. |
| <p/> |
| Upon the successful establishment of the IPsec tunnel, the updown script automatically |
| inserts iptables-based firewall rules that let pass the tunneled traffic. |
| In order to test both tunnel and firewall, client <b>alice</b> behind gateway <b>moon</b> |
| pings client <b>bob</b> located behind gateway <b>sun</b>. |
