the remote VPN gateway requests a phase one lifetime of 168 hours - pretty long in my opinion ;-)
I assume that you are on version two and you cannot influence the timers manually, so the only way is to ask the remote admin to change this value to 28800 (ISAKMP IKE LIFETIME), by the way the timer for Phase 2 is 3600s (IPSEC SA LIFETIME) in version 2.
Even in version 3 the maximum lifetime for phase one is 28800s.
