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.

A connection between the subnets behind the gateways <b>moon</b> and <b>sun</b> is set up.
|
||||
The authentication is based on trustworthy public keys stored as <b>CERT</b>
|
||||
resource records in the Domain Name System (DNS) and protected by <b>DNSSEC</b>.
|
||||
<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 both tunnel and firewall, client <b>alice</b> behind gateway <b>moon</b>
|
||||
pings client <b>bob</b> located behind gateway <b>sun</b>.
