testing: Reorganizing IKEv1 and IKEv2 examples
For documentation purposes the new folders ikev1-algs, ikev2-algs, ikev1-multi-ca and ikev2-multi-ca have been created. Most of the test cases have now been converted to the vici interface. The remaining legacy stroke scenarios yet to be converted have been put into the ikev2-stroke-bye folder. For documentation purposes some legacy stroke scenarios will be kept in the ikev1-stroke, ikev2-stroke and ipv6-stroke folders.

The roadwarriors <b>alice</b> and <b>venus</b> sitting behind the NAT router <b>moon</b> set up
|
||||
tunnels to gateway <b>sun</b>. UDP encapsulation is used to traverse the NAT router.
|
||||
Authentication is based on X.509 certificates.
|
||||
<p/>
|

Upon the successful establishment of the IPsec tunnel, <b>leftfirewall=yes</b> automatically
|

inserts iptables-based firewall rules that let pass the tunneled traffic. In order to test the tunnel,
|

the NAT-ed hosts <b>alice</b> and <b>venus</b> ping the client <b>bob</b> behind the gateway <b>sun</b>.
