LAN1==>CISCO ROUTER 1841==>ADSL MODEM ============  Internet  =============WIMAX MODE=====>CISCO ASA=====>LAN2

on my cisco router, when issuing sh cry is sa, I keep have :

dst                         src              state                   conn-id   slot

x.x.x.x                y.y.y.y           MM_NO_STATE        174     0        (deleted)

and when issuing debug crypto isakmp, I have:
