| The roadwarrior <b>carol</b> and the gateway <b>moon</b> use the <b>openssl</b> |
| plugin based on the <b>OpenSSL</b> library for all cryptographical and X.509 |
| certificate functions whereas roadwarrior <b>dave</b> uses the default <b>strongSwan</b> |
| cryptographical plugins <b>aes sha1 sha2 hmac gmp x509</b> plus the <b>openssl</b> |
| plugin for the Elliptic Curve Diffie-Hellman groups only. |
| <p> |
| The roadwarriors <b>carol</b> and <b>dave</b> set up a connection each |
| to gateway <b>moon</b>. The authentication is based on <b>X.509 certificates</b>. |
| <b>carol</b> proposes the DH groups ECP_256 and ECP_384 whereas <b>dave</b> proposes |
| ECP_256 and ECP_521. Since <b>moon</b> does not support ECP_256 the roadwarriors |
| fall back to ECP_384 and ECP_521, respectively. |
| <p> |
| Upon the successful establishment of the IPsec tunnels, the updown script automatically |
| inserts iptables-based firewall rules that let pass the tunneled traffic. |
| In order to test both tunnel and firewall, both <b>carol</b> and <b>dave</b> ping |
| the client <b>alice</b> behind the gateway <b>moon</b>. |
