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 functions
|
||||
whereas roadwarrior <b>dave</b> uses the default <b>strongSwan</b> cryptographical
|
||||
plugins <b>aes des sha1 sha2 md5 gmp</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, <b>leftfirewall=yes</b>
|
||||
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>.
