In theory both ends are supposed to negotiate and select the smallest lifetime between the hosts. Reality is quite different, there are as many implementations of IPSec as there are debices implementing it, or close. And connecting in IPSec with a Cisco or a Checkpoint can be quite tedious. My opinion : avoid unnecessary headaches : put the same lifetime on both ends. > - Can key lifetime be configured per host-host connection? Yes. Jerome Herman > > Thanks, Erik > >
