The roadwarriors <b>carol</b> and <b>dave</b> set up a connection to gateway <b>moon</b>.
|
||||
The authentication is based on Pre-Shared Keys (<b>PSK</b>)
|
||||
followed by extended authentication (<b>XAUTH</b>) of <b>carol</b> and <b>dave</b>
|
||||
based on user names and passwords.
|
||||
<p>
|
||||
Upon the successful establishment of the IPsec tunnel, leftfirewall=yes automatically
|
||||
inserts iptables-based firewall rules that let pass the tunneled traffic.
|
||||
In order to test both tunnel and firewall, <b>carol</b> and <b>dave</b> ping the client
|
||||
<b>alice</b> behind the gateway <b>moon</b>.
