Hi, while implementing IPSec on our Routers I got some questions regarding lifetimes of Proposals. It would be great, if someone could help me. What will be the typical practice, when using more than one Ipsec protocol in combination, e.g. ESP+AH with seperate configurable lifetimes? Just to use only one lifetime (and which?) for all protocols or to use different lifetimes for each? Thanks a lot Christian
