The roadwarriors <b>carol</b> and <b>dave</b> each set up a connection to gateway <b>moon</b>.
<b>carol</b>'s authentication is based on a Pre-Shared Key (<b>PSK</b>) whereas <b>dave</b>'s
is based on an RSA signature (<b>RSASIG</b>). Gateway <b>moon</b> supports both authentication modes
and automatically selects the correct roadwarrior connection definition based on policy
information gained from pre-parsing the peers' ISAKMP proposal payload.
