Annotation of embedaddon/strongswan/testing/tests/ikev1/virtual-ip/description.txt, revision 1.1.1.1

1.1       misho       1: The roadwarriors <b>carol</b> and <b>dave</b> both set up a connection to gateway <b>moon</b>.
                      2: The roadwarriors each unilaterally define a static virtual IP using the <b>leftsourceip</b>
                      3: parameter. In order to detect potential address conflicts, the roadwarriors send
                      4: their virtual IPs embedded in an IKEv1 Mode Config payload to <b>moon</b> for verification.
                      5: In our scenario <b>moon</b> accepts the address choices thus allowing <b>carol</b> and
                      6: <b>dave</b> to install their respective virtual IP addresses.
                      7: <p>
                      8: In order to test the tunnels both <b>carol</b> and <b>dave</b> ping the client <b>alice</b>
                      9: behind the gateway <b>moon</b> as well as the inner interface of the gateway.
                     10: The latter ping requires access to the gateway itself which is granted by the
                     11: directive <b>lefthostaccess=yes</b>. The source IP of the two pings will be the virtual
                     12: IP addresses <b>carol1</b> and <b>dave1</b>, respectively. Also thanks to the automatically
                     13: configured source route entries, <b>moon</b> is able to ping both roadwarriors by using the
                     14: established net-net IPsec tunnels.
